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: max8998: Add irq domain support 
This patch adds irq domain support for max8998 interrupts.

To keep both non-DT and DT worlds happy, simple domain is used, which is
linear when no explicit IRQ base is specified and legacy, with static
mapping, otherwise.

regulator: Support MAX8998/LP3974 DVS-GPIO 
The previous driver did not support BUCK1-DVS3, BUCK1-DVS4, and
BUCK2-DVS2 modes. This patch adds such modes and an option to block
setting buck1/2 voltages out of the preset values.

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.
