soc: espressif: fix optimization flag boot fault

Browse source 
When DEBUG_OPTIMIZATION or NO_OPTIMIZATION is
enabled, efuse reading fails during bootloader start.
Move those calls into IRAM area so that reading when
cache is disabled works without any faults.

In HAL side, we need to use low level calls to read
CPU id instead of Zephyr's default one.
