regulator: qpnp-amoled: Update AOD mode configuration

As per the hardware recommendation, apply the AOD configuration
only when the display driver requests for AOD exit and then apply
the normal configuration 10 ms after SWIRE is high. Also, update
the pulse skip threshold for AOD mode along with the maximum time
to poll for VREG_OK to 100 ms.
