Looks like this also needs
	depends on HAS_IOMEM

since everything in drivers/mfd/Kconfig depends on HAS_IOMEM and
since this 'select' causes a kconfig warning when HAS_IOMEM is not set:

WARNING: unmet direct dependencies detected for MFD_SIMPLE_MFD_I2C
  Depends on [n]: HAS_IOMEM [=n] && I2C [=y]
  Selected by [y]:
  - JOYSTICK_SENSEHAT [=y] && INPUT_JOYSTICK [=y] && INPUT [=y] && I2C [=y]
