Power rails of some peripherals are controlled externally. This is a case in embedded controllers, where the power of some I2C devices are managed by the main application processor. To ensure that zephyr drivers access the devices where is powered on, introduce a "monitoring" power domain. It works by registering interrupt handler with gpio a pin, so that when power state changes, it will notify relevant drivers. Additionaly add CONFIG_POWER_DOMAIN_INIT_PRIORITY to replace harcoded init priority. Fixes: #51349 Signed-off-by: Albert Jakieła <jakiela@google.com>
