mfd: Add support for TWL4030/5030 dynamic power switching
The TWL4030/5030 family of multifunction devices allows board-specific
control of the the various regulators, clock and reset lines through
'scripts' that are loaded into its memory. This allows for Dynamic Power
Switching (DPS).
Implement board-independent core support for DPS that is then used by
board-specific code to load custom DPS scripts.

+ Say yes here if you want to use the power resources on the
+ TWL4030 family chips. Most of these resources are regulators,
+ which have a separate driver; some are control signals, such
+ as clock request handshaking.
+
+ This driver uses board-specific data to initialize the resources
+ and load scripts controling which resources are switched off/on
+ or reset when a sleep, wakeup or warm reset event occurs.
