media: i2c: ds90ub960: Move UB9702 registers to a separate section

Browse Source 
The driver supports both UB960 and UB9702. While devices work in similar
ways and have a lot of identical registers, there are also plenty of
differences.

To clarify the situation a bit, move the UB9702 registers to a separate
section and prefix them with UB9702.
