Lots of build errors for drivers/pinctrl/mediatek/pinctrl-moore.c when
CONFIG_OF is not enabled (but COMPILE_TEST is).

first this:
WARNING: unmet direct dependencies detected for PINCTRL_MTK_MOORE

  Selected by [y]:
  - PINCTRL_MT7623 [=y] && PINCTRL [=y] && (ARCH_MEDIATEK || COMPILE_TEST [=y]) && (MACH_MT7623 || COMPILE_TEST [=y])
