soc: esp32xx: refactor clock and RTC subsystems

Browse source 
The RTC subsystem in espressif's SOCs, among other tasks
is responsible for clock selection for CPU and for low
power domain clocks such as RTC_SLOW and RTC_FAST.

This commit allows for proper clock source and rate
selection for CPU, using the espressif,riscv and
espressif,xtensa-lx6/7 bindings.

It also enables clock selection for RTC_FAST and RTC_SLOW,
that impacts some peripherals, such as rtc_timer.
