Wangjialin fad639f0d4 feature(psram): update psram initialization. 
1. use spi functions in rom
2. remove unnecessary GPIO configurations.
3. remove unnecessary dummy settings.
4. enable dummy out function
5. flash and psram have independent timing setting registers.
6. no need to set 1.9v for LDO in 80Mhz
7. set IO driver ability to 1 by default.
8. no need to use GPIO matrix on esp32s2, IO MUX is recommended
9. enable spi clock mode and IO mode settings

Bootloader Support Component
============================

Overview
--------

"Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app.

Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
