Move the following subdevices to use the pm8xxx interface - mpp, irq, gpio, keypad, power-key, leds, othc, vibrator, rtc, batt-alarm, thermal, upl, nfc, pwm, xoadc, regulators, xo-buffers, charger. This allows usage of a common driver for modules which are same across multiple PM8XXX PMICs. It also provides flexibility to add/remove subdevices for multiple board configurations.
