While trying to test this, I found that I am not able to test-compile
these drivers. The problem is in drivers/soc/Makefile:

obj-$(CONFIG_ARCH_MEDIATEK) += mediatek/

So while Kconfig lets me select the drivers when COMPILE_TEST is
enabled, the build system itself ignores the directory in which these
drivers reside and they aren't built.

If you really want your drivers to be test-compilable then you must
change the above to:

obj-y += mediatek/

I'll send a patch.

Your patch itself looks good to me.
