mfd: twl4030-gpio driver
This adds basic support for the GPIOs in the twl4030 power management
chip. That includes two open drain LED drivers, and the use of GPIO-0
(and GPIO-1) as MMC/SD card detect switches which can control whether
the VMMC1 (and VMMC2) regulators are active.
This version of the code has a debounce call that will probably be
replaced before long, when a more generic interface exists.
