The AC charger plug-in detection while booting causes I2C read
failure if AC charger is not connected. Now the LPN pin is enabled
for every PM2301 register access, which solves the issue.

AB and PMxxx doesn't have same watchdog refresh period. Add watchdog
to refresh period parameters in x500 charger structure, this should
kick watchdog every 30sec. The AC charging should also kick both
