[patch] drivers, mfd: fix link error

From: David Rientjes
Date: Thu Mar 21 2013 - 15:08:40 EST

CONFIG_MFD_CROS_EC requires CONFIG_MFD_CORE for a couple of functions that
are declared but not defined:

ERROR: "mfd_remove_devices" [drivers/mfd/cros_ec.ko] undefined!
ERROR: "mfd_add_devices" [drivers/mfd/cros_ec.ko] undefined!

Fix it by selecting CONFIG_MFD_CORE anytime CONFIG_MFD_CROS_EC is enabled.
