Should indeed depend on ARM64.

Those are the main clock controllers. Like for other AML SoC families,
they are necessary to boot the device which is why they use 'default y'

Is it a problem ?

The whole meson directory depends on ARCH_MESON, so the drivers will go
away if Amlogic support is removed on ARM64.
