clk: rs9: Support device specific dif bit calculation

Browse source

The calculation DIFx is BIT(n) +1 is only true for 9FGV0241. With
additional devices this is getting more complicated.
Support a base bit for the DIF calculation, currently only devices
with consecutive bits are supported, e.g. the 6-channel device needs
additional logic.
