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.

This driver provides an in-kernel interface to those GPIOs using
