mfd: Kontron PLD mfd driver

Add core MFD driver for the on-board PLD found on some Kontron embedded
modules. The PLD device may provide functions like watchdog, GPIO, UART
and I2C bus.

The following modules are supported:
	* COMe-bIP#
	* COMe-bPC2 (ETXexpress-PC)
	* COMe-bSC# (ETXexpress-SC T#)
	* COMe-cCT6
	* COMe-cDC2 (microETXexpress-DC)
	* COMe-cPC2 (microETXexpress-PC)
	* COMe-mCT10
	* ETX-OH

           Say yes here if you want support for the ADC unit in the JZ4740 SoC.
           This driver is necessary for jz4740-battery and jz4740-hwmon driver.
