How to reproduce the problem:
$ make tinyconfig
$ make menuconfig
then enable:
 CONFIG_COMPILE_TEST=y
 CONFIG_PINCTRL=y
and any of these:
 CONFIG_PINCTRL_MT7622=y
 CONFIG_PINCTRL_MT7629=y
 CONFIG_PINCTRL_MT7623=y

This combination causes build failure.

Fix the problem by making PINCTRL_MT76XX to depend on CONFIG_OF=y.
