meta-ampere: mtmitchell: fix Host is powered OFF when BMC reboots

When BMC is rebooted, because PSON_L has pull up to P3V3_STB, it changes its
value to HIGH which causes the Host is turned OFF.
Add code to check P3V3_STB and recover PSON_L to correct state before setting
BMC_RDY.

Tested:
1. Turn ON the Host
2. Run BMC reboot stress test and check if the Host is still ON
