regulator: max8997: Convert to GPIO descriptors

This rewrites the max8997 regulator driver to fetch the dvs
regulators as descriptors. This will likely mostly come from
the device tree since there are no in-tree users of the platform
data, but supplying GPIO descriptor tables from board files is
also possible if needed.

Input: max8997 - convert to modern way to get a reference to a PWM

pwm_request() isn't recommended to be used any more because it relies on
global IDs for the PWM which comes with different difficulties.

The new way to do things is to find the right PWM using a reference from
the platform device. (This can be created either using a device-tree
or a platform lookup table, see e.g. commit 5a4412d4a82f ("ARM: pxa:
tavorevb: Use PWM lookup table") how to do this.)

There are no in-tree users, so there are no other code locations that need
adaption.

mfd: max8997: Enale irq-wakeup unconditionally

IRQ wake up support for MAX8997 driver was initially configured by
respective property in pdata. However, after the driver conversion to
device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD
drivers initialized from device-tree assume that they can be an irq wakeup
source, so enable it also for MAX8997. This fixes support for wakeup from
MAX8997 RTC alarm.

This patch enables IRQ handling for MAX8997/8966 chips.

Please note that Fuel-Gauge-related IRQs are not implemented in this
initial release. The fuel gauge module in MAX8997 is identical to
MAX17042, which is already in Linux kernel. In order to use the
already-existing MAX17042 driver for fuel gauge module in MAX8997, the
main interrupt handler of MAX8997 should relay related interrupts to
MAX17042 driver. However, in order to do this, we need to modify
MAX17042 driver as well because MAX17042 driver does not have any
interrupt handlers for now. We are not going to implement this in this
initial release as it is not crucial in basic operations of MAX8997.

regulator: MAX8997/8966 support

This patch supports PMIC/Regulator part of MAX8997/MAX8966 MFD.
In this initial release, selecting voltages or current-limit
and switching on/off the regulators are supported.

Controlling voltages for DVS with GPIOs is not implemented fully
and requires more considerations: it controls multiple bucks (selection
of 1, 2, and 5) at the same time with SET1~3 gpios. Thus, when DVS-GPIO
is activated, we lose the ability to control the voltage of a single
buck regulator independently; i.e., contolling a buck affects other two
bucks. Therefore, using the conventional regulator framework directly
might be problematic. However, in this driver, we try to choose
a setting without such side effect of affecting other regulators and
then try to choose a setting with the minimum side effect (the sum of
voltage changes in other regulators).

On the other hand, controlling all the three bucks simultenously based
on the voltage set table may help build cpufreq and similar system
more robust; i.e., all the three voltages are consistent every time
without glitches during transition.
