[PATCH v2] regulator: RT5133: add missing HAS_IOMEM dependency

[Randy Dunlap]

When building on ARCH=um (which does not set HAS_IOMEM), kconfig
reports an unmet dependency caused by REGULATOR_RT5133. It selects
OF_GPIO, which depends on HAS_IOMEM. To stop this warning,
REGULATOR_RT5133 should also depend on HAS_IOMEM.

kconfig warning:
WARNING: unmet direct dependencies detected for OF_GPIO
  Depends on [n]: GPIOLIB [=y] && OF [=y] && HAS_IOMEM [=n]
  Selected by [y]:
  - REGULATOR_RT5133 [=y] && REGULATOR [=y] && I2C [=y] && GPIOLIB [=y] && OF [=y]
