regulator: max8998: Convert to GPIO descriptors

This rewrites the max8998 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.

regulator: max8998: Add charger regulator

The max8998 has a current regulator for charging control. The
charger driver in drivers/power/supply/max8998_charger.c has a
comment in it stating that 'charger control is done by a current
regulator "CHARGER"', but this regulator was never added until
now.

The current values have been extracted from a downstream driver
for the SGH-T959V.

regulator: max8998: Use arrays for specifying voltages in platform data

This patch modifies the platform data of max8998 to use arrays for
specifying predefined voltages of buck1 and buck2 instead of separate
field for each voltage.

This allows to simplify the code a bit and will help in adding support
for Device Tree, which will be introduced in further patch.

mfd: Support LP3974 RTC

The first releases of LP3974 have a large delay in RTC registers,
which requires 2 seconds of delay after writing to a rtc register
(recommended by National Semiconductor's engineers)
before reading it.

If "rtc_delay" field of the platform data is true, the rtc driver
assumes that such delays are required. Although we have not seen
LP3974s without requiring such delays, we assume that such LP3974s
will be released soon (or they have done so already) and they are
supported by "lp3974" without setting "rtc_delay" at the platform
data.

This patch adds delays with msleep when writing values to RTC registers
if the platform data has rtc_delay set.
