power button: Wait for charger and battery initialization
For PWRBTN_STATE_INIT_ON, before attempting to power the
system on, we need to wait for charger and battery to be
ready to supply sufficient power. Check every 100
milliseconds, and give up after 1 second. This allows
time for charger, battery and USB-C PD initialization.
Previously, init-on would fail because it called
set_pwrbtn_to_pch too soon (before charge current had
been initialized, and before the USB-C 3A current was
detected).
