479af576ca ulp: fix calculation or ulp_run argument
The argument to ulp_run should be expressed in 32-bit words. Both the
address of ulp_entry and RTC_SLOW_MEM already are uint32_t*, so their
difference is the difference in addresses divided by sizeof(uint32_t).
Therefore the extra division by sizeof(uint32_t) is not needed.

4b97a1edb2 ulp example: fix for RTC IOs
- call rtc_gpio_init for pins which aren't configured as RTC by default
- for RTC IOs 16 and 17, read higher part of the input register
- automatically convert GPIO number into RTC IO number
- use ulp_set_wakeup_period instead of writing to register

af6cfc5552 docs, examples: use rtc_gpio_isolate to disconnect GPIO12
This is needed to reduce deep sleep current on ESP32-WROVER modules.

Ref TW18165.

3c583a7655 sdkconfig: set CONFIG_ESP32_DEEP_SLEEP_WAKEUP_DELAY=2000 by default
To increase the chances that the examples work out of the box, this
change is raising the default deep sleep wakeup delay to 1ms.
If GPIO15 is low at startup, ROM code takes less time to execute
(because no logging is performed), so more time may be needed to allow
flash chip to become ready.
