Martin Blumenstingl 33d0fcdfe0 clk: gxbb: add the SAR ADC clocks and expose them
The HHI_SAR_CLK_CNTL contains three SAR ADC specific clocks:
- a mux clock to choose between different ADC reference clocks (this is
  2-bit wide, but the datasheet only lists the parents for the first
  bit)
- a divider for the input/reference clock
- a gate which enables the ADC clock

Additionally this exposes the ADC core clock (CLKID_SAR_ADC) and
CLKID_SANA (which seems to enable the analog inputs, but unfortunately
there is no documentation for this - we just mimic what the vendor
driver does).
