8de9149b11 component/bt: bugfix of bluetooth modem sleep not being able to work with Dynamic Frequency Scaling
1. start an esp_timer on entering sleep to acquire pm_lock before wake up from modem sleep
2. decrease the clock division of XTAL fed to bluetooth low power clock from 32us to 2us period to allow to work under 240MHz Max CPU frequency
3. decrease the minimum sleep duration threshold to allow shorter bluetooth modem sleep period, especially for BLE with short connection interval
4. reconfigure bluetooth baseband(BT-BB) settings after PHY/RF init upon waking up from modem sleep to avoid packet RX/TX performance degradation

4abe47437f components/bt: Fix broken API esp_bt_mem_release() for parameter ESP_BT_MODE_BTDM
Problem:
The new API esp_bt_mem_release() that was added freed BTDM data to heap from esp_bt_controller_mem_release().
Now with the BT memory optimization commit ee787085f9,
the BTDM data is optimized and reduced to only 32 bytes which is not sufficient amount to be added to heap.
So, using the API leads to assert saying that the region is too small.

Solution:
Modify heap_caps_add_region_with_caps to return ESP_ERR_INVALID_SIZE in case the range is too small to create a new heap.
Do not assert if return value is ESP_ERR_INVALID_SIZE

This also fixes using API esp_bt_controller_mem_release() with ESP_BT_MODE_BTDM

afa091fe79 prevent heap_caps_add_region exception if region is empty
Calling `esp_bt_controller_mem_release` or `esp_bt_mem_release` might result in exception if any of the regions returned to heap are empty. This happens usually if BT/BLE is enabled, but not used/linked in the final firmware.

ee787085f9 component/bt : decrease memory consumption by conn number
1. BLE only with 9(max) connection will decrease 3K DRAM
2. BR/EDR only with 7(max) connection will decrease 16K DRAM
3. Any of BLE or BR/EDR connection number decrease will also decrease DRAM consumption
4. Decrease one BLE connection will save about 1KB DRAM
5. Decrease one BR/EDR ACL connection will save about 1.2KB DRAM
6. Decrease one BR/EDR SCO/eSCO will save 2KB DRAM.
7. fix some definition and kconfig
8. remove 1.2k of vhci tx cache and make .bss & .data to heap about 1.4K
9. modify BT Reserved Memory size and modify example to support new bt kconfig

a5ae5ac4b3 soc: Allow components to reserve fixed memory ranges that they need
No longer necessary to keep all reserved addresses in 'soc'.

Means 'soc' does not need to know about 'bt', for example.

Also means that Bluetooth can be enabled in config without any memory being reserved for BT
controller. Only if code calling the BT controller is linked in, will this memory be reserved...

6e4342a877 bt : fix bug that bluetooth controller init/disable/enable/disable may cause exception
1. when one task do deinit/init/disable/enable, especially different cpu
core, it may cause controller crash in ISR handler
2. fix while BLE is scanning, bluetooth controller is disabled cause BLE
scan is not abort.

f610249bdd Reclaim BT/BTDM BSS and Data in bluetooth memory release function
1. Modify esp_bt_controller_mem_release() to release BTDM BSS and Data to heap if
ESP_BT_MODE_BTDM mode is passed to it
2. Add a new API esp_bt_mem_release() which internally calls
esp_bt_controller_mem_release() with the provided mode and then if mode
is ESP_BT_MODE_BTDM, releases BT BSS and Data to heap.

Background:
For Wi-Fi and BT/BLE applications, for e.g. the usecase is like when
Bluetooth is used for provisioning and once the device is connected to the Wi-Fi
AP, we can turn off Bluetooth completely. In such scenarios, it should be possible to
reclaim all the memory of Bluetooth. Although, currently this does not
happen.

Experiment:
Made the following modifications to examples/bluetooth/gatt_server :
1. Added support of simple_wifi to it
2. Moved all the bluetooth related code under CONFIG_BT_ENABLED config
option
3. Calculated the free heap in 2 similar scenarios:
   i. Disabled BT (CONFIG_BT_ENABLED undefined) and checked the free
heap after STA connected
   ii. Kept BT enabled and disabled it after STA connected and checked
the free heap
Ideally, the numbers for i., ii. above should have been similar. But
there was a delta of almost 30-31K. (i. > ii.)
4. Through make size-components checked the common BSS for libbta.a and libbtdm_app.a
and found it to be almost 30K. Data is around 1K

Solution:
1. Modified the linker script to mark the BSS and Data for these libraries and
free it when ESP_BT_MODE_BTDM mode is passed to mem release APIs.
2. Verified that the free heap is comparable for i. and ii. above.

Note: It is known that once this is done, Bluetooth can only be used
again post reboot.

e3df7d97a7 esp32: fix coex bug
1. fix BLE connection missing in coex mode
    2. modify other parameters to make coex priority more reasonable
    3. fix modem sleep procedure trap cause Wifi disable RF when BT is
    working. Such cause that BR/EDR is difficult to be connected, BLE
    connection stability decrease and so on.
    4. modify BR/EDR coexist duration to imrove BR/EDR connect success
    ratio.
    5. Due to the hardware coexist bug, BLE scan interval/window should
    be less than 0x100(about 160ms). Therefore, it will cause BLE cannot
    scan any advertising packet while WiFi have higher priority
    behaviour(such like RX beacon, scan, TX/RX VO packets and etc.).
