hwmon: Add ST-Ericsson ABX500 hwmon driver
Each of ST-Ericsson X500 chip set series consists of both ABX500 and DBX500 chips. This is ABX500 hwmon driver, where the abx500.c is a common layer for all ABX500s, and the ab8500.c is specific for AB8500 chip. Under this designed structure, other chip specific files can be added simply using the same common layer abx500.c.

+Description
+-----------
+
+Every ST-Ericsson Ux500 SOC consists of both ABx500 and DBx500 physically,
+this is kernel hwmon driver for ABx500.
+
+There are some GPADCs inside ABx500 which are designed for connecting to
+thermal sensors, and there is also a thermal sensor inside ABx500 too, which
+raises interrupt when critical temperature reached.
+
+This abx500 is a common layer which can monitor all of the sensors, every
+specific abx500 chip has its special configurations in its own file, e.g. some
+sensors can be configured invisible if they are not available on that chip, and
+the corresponding gpadc_addr should be set to 0, thus this sensor won't be
+polled.
