mfd: pm8058: Modify pm8058 subdevices to pm8xxx interface

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.
