We can't really do much for the compatible, and it's the standard
practice there anyway. However, it looks much more common for Kconfig to
have a pattern like $FRAMEWORK_$SOC, so maybe we could just rename the
Kconfig (and drivers name) to CCU_SUN50I_A64? It's not been exposed to
the defconfig so far anyway, so we can change them without any real harm

Otherwise, yeah, we can do what Stephen suggested
