Ivan Grokhotkov 83184bd52b deep sleep: RTC fast memory may be disconnected after deep sleep wakeup
This adds a workaround for a bug that following deep sleep wakeup, ISO (bus isolation) signal may be set for RTC fast memory.
We set FORCE_NOISO bit in RTC_CNTL_PWC_REG until we find out what is causing ISO signal to be set.

Ivan Grokhotkov b3f6cd08db support for console redirection to other UART
This change adds a set of menuconfig options to set custom UART#, baud rate, and pins, for console output.
Setting happens in bootloader startup code for PRO CPU, and in application startup code for APP CPU.

Ivan Grokhotkov 5ab769516d components/esp32: add CPU frequency selection in menuconfig
Note that with WiFi stack enabled, system_init will reset frequency to 240MHz.
To make this setting useful, esp32-wifi-libs submodule needs to be updated.
