Subject: [PATCH] mfd: add missing MODULE_DESCRIPTION() macros

On x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/arizona.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/pcf50633-gpio.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/timberdale.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/ssbi.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/rt4831.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/intel_soc_pmic_bxtwc.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes mfd-core.c and vexpress-sysreg.c which, although they
did not produce a warning with the x86 allmodconfig configuration, may
cause this warning with other configurations.
