zephyr: ap_pwrseq: support host sleep event and wake mask
S0ix enablement has multiple patches, this is second one
of the series.
HC EC_CMD_HOST_SLEEP_EVENT implementation in legacy EC code is reused.
This will be migrated to Zephyr implementation.
ap_pwrseq provides ap_power_chipset_handle_host_sleep_event() to
process host sleep event changes.
BIOS sets wake masks for each sleep state (S3/S5/S0ix) only once during
boot up. EC has to take care wake mask update when power state changes.
Updating wake mask at run time is added to ap_pwrseq.
HC get/set wake mask in legacy EC code is resued. This should migrate
to Zephyr implementation too. Refer to CL:576047 for original design.
