The MAX8998 chip have regulator and rtc features. The i2c slave address
of regulator and rtc is different, so needs each i2c client on i2c
operation functions.

Also, this patch exports i2c operation functions instead of callback to
make easy to read.

GPIOs on these controller are multi-functional. If you decided to use
some of them e.g. as input channels for the ADC, you surely don't want
those pins to be reassigned as simple GPIOs (which may be triggered even
from userspace via 'export'). Same for the touchscreen controller pins.
Since knowledge about the hardware is needed to decide which GPIOs to
reserve, let this bitmask be inside platform_data and provide some
defines to assist potential users.

I have a regulator A that sets regulator B as its supply. When I call
set_supply to add B as the supply for A, regulator A gets added to the
supply_list for regulator B.

When I call regulator_disable(A), I end up with a call chain like this:

regulator_disable(A)
> mutex_lock(A)
> _regulator_disable(A)
>> _regulator_disable(B)
>>> _notifier_call_chain(B)
>>>> mutex_lock(A)

Which results in dead lock since we are trying to acquire the mutex lock
for regulator A which we already hold.

This patch addresses this issue by moving the call to disable regulator
B outside of the lock aquired inside the initial call to
regulator_disable.

This change also addresses the issue of not acquiring the mutex for
regulator B before calling _regulator_disable(B).

MAX8952 PMIC is used to provide voltage output between 770mV - 1400mV
with DVS support. In this initial release, users can set voltages for
four DVS modes, RAMP delay values, and SYNC frequency.
Controlling FPWM/SYNC_MODE/Pull-Down/Ramp Modes and reading CHIP_ID
is not supported in this release.

If GPIO of EN is not valid in platform data, the driver assumes that it
is always-on. If GPIO of VID0 or VID1 is invalid, the driver pulls down
VID0 and VID1 to fix DVS mode as 0 and disables DVS support.

We assume that V_OUT is capable to provide every voltage from 770mV to
1.40V in 10mV steps although the data sheet has some ambiguity on it.
