[PATCH] pinctrl: imx: select regmap subsystem

[Arnd Bergmann <arnd@arndb.de>]

Building the imx pinctrl driver without regmap fails with multiple
build errors like:

drivers/pinctrl/freescale/pinctrl-imx.c: In function 'imx_pinctrl_probe':
drivers/pinctrl/freescale/pinctrl-imx.c:723:9: error: variable 'config' has initializer but incomplete type
  struct regmap_config config = { .name = "gpr" };

This adds a 'select REGMAP' statement, to ensure we can define a 'struct
regmap_config'. This matches what all other regmap users do. The driver
actually uses syscon on top of regmap, but syscon is already enabled
on i.MX for other reasons, and selecting REGMAP but not SYSCON is
sufficient for build testing on other platforms.
