I can split this into two commits, first the .c files and then the .h
files, so everything is a 100% rename, if that makes a difference.

Autoloading should work anyway, since there is a module alias for the
compatible string. This change is more about the principle of least
surprise. The compatible is allwinner,sun50i-a64-ccu, the Kconfig symbol
is SUN50I_A64_CCU, the driver name (in /sys/bus/platform/drivers) is
sun50i_a64_ccu, but yet the module name is ccu-sun50i-a64???

Once we allow building modules, the names are ABI, and this
inconsistency will bother me until the end of time :)

If there is a way to completely rename the module without renaming the
files (not adding an alias), then that would be enough for me.

Regards,
Samuel
