Subject: linux-next: build failure after merge of the gpio tree

Hi Linus,

After merging the gpio tree, today's linux-next build (arm
orion5x_defconfig) failed like this:

drivers/gpio/gpio-mvebu.c:1062: undefined reference to `__devm_regmap_init_mmio_clk'
drivers/gpio/gpio-mvebu.c:1078: undefined reference to `__devm_regmap_init_mmio_clk'

Caused by commit

  2233bf7a92e7 ("gpio: mvebu: switch to regmap for register access")

Presumably a missing Kconfig dependency.  Yeah, CONFIG_REGMAP_MMIO is
not set for this build.
