The chip register layout has nothing to do with MIPI DCS, the registers
incorrectly marked as MIPI DCS in the driver are regular chip registers
often with completely different function.

Fill in the actual register names and bits from [1] and [2] and add the
entire register layout, since the documentation for this chip is hard to
