Subject: [PATCH 3/4] mfd: palmas: reset pm_power_off if it is set for the device

If Palams supports the system power controller and pm_power_off
is implemented through the Palmas driver then reset the pm_power_off
in driver remove.

This will avoid the call of Palmas driver after removal of driver.
