drivers/i2c/ck505: Add generic driver to configure clockgen

Replaces the ics/954309 driver with a more generic version to
accommodate clockgens with a different amount of registers.

It also features a mask to only touch certain bits of the clockgen.

TODO: set appropriate mask for X60/T60 since the datasheets for their
clockgens can be found.
