dts: riscv: espressif: esp32: move power-states to soc dts files

Browse source 
CPU idle states are not board specific. This patch moves ESP32 idle
states to the core SoC dts files. Board can always tweak some state
parameters (if needed), but the definition belongs to core SoC dts
files, same as e.g. peripherals.
