power: qpnp-qg: Update PON_OCV and GOOD_OCV handling 



The QG HW state machine based on the reset / PON conditions
updates the PON SOC at different HW registers. Add the SW
logic to read the PON SOC from LAST_S3 / SDAM / S7_PON
registers.

While at it, enable the GOOD_OCV IRQ only when APPS is not
in sleep.
