Building multi_v7_defconfig for mx6 causes the following build error:

  CC      drivers/mfd/syscon.o
drivers/mfd/syscon.c:94: error: variable 'syscon_regmap_config' has initializer but incomplete type

drivers/mfd/syscon.c:126: warning: assignment makes pointer from integer without a cast

Fix it by selecting REGMAP option.
