target: msm8226 : Check pon hard reset bit as a part of charger mode check.
There was a recent change in the kernel pmic driver after which adb reboot
now triggers a cold reboot. Hence our earlier check where we were relying on
the PMIC warmboot status register is not enough anymore. We need to check the
pon hard reset bit as well.
