mfd: Add STMPE I/O Expander support 



Add support for the STMPE family of I/O Expanders from
STMicroelectronics.  These devices include upto 24 gpios and a varying
selection of blocks, including PWM, keypad, and touchscreen controllers.
This patch adds the MFD core.

	  Support for the STMPE family of I/O Expanders from

	  STMicroelectronics.



	  Currently supported devices are:



		STMPE811: GPIO, Touchscreen

		STMPE1601: GPIO, Keypad

		STMPE2401: GPIO, Keypad

		STMPE2403: GPIO, Keypad



	  This driver provides common support for accessing the device,

	  additional drivers must be enabled in order to use the functionality

	  of the device.  Currently available sub drivers are:



		GPIO: stmpe-gpio

		Keypad: stmpe-keypad

		Touchscreen: stmpe-ts
