SG2000 series SoC has the same clock as CV1810 series, but the clock
related to A53 is functional in SG2000 series. So a new compatible
string is needed for the new SoC.
Add definition for the clock controller of the SG2000 series SoC.

Add driver skeleton for CV1800/SG2000 series clock controller.
The skeleton code includes:
1. common utility code for clk_ops implementation
2. basic probe code of the whole driver
3. helper structure for clk definition

Add clock generator node for CV1800B and CV1812H.
Until now, It uses DT override to minimize duplication. This may
change in the future. See the last link for the discussion on
maintaining DT of CV1800 series.
