Use of_device_get_match_data() instead please.

This "multi-device" driver design is sort of odd. Why not have
different files and struct drivers for the different devices in
the system that are clock controllers? I don't really understand
why we're controlling the devices with one struct driver
instance. Is something shared between the devices?

You can drop these MODULE_* things as they're not going to be
used in builtin only code.
