Hi Geert,

Because it's a ARM64 driver, ARM64 will select COMMON_CLK.
It seems that some dependency should be checked if COMPILE_TEST is
enabled and the driver is compiled on non-ARM64 environment.
We don't expect the driver can be used on non-ARM64 environment,may I
remove COMPILE_TEST to solve the problem?
If the driver only depends on ARCH_MEDIATEK, it must be compiled on
ARM64.

Thanks,
Trevor
