clk: qcom: gcc-sc8180x: Register QUPv3 RCGs for DFS on sc8180x

QUPv3 clocks support DFS on sc8180x platform but currently the code
changes for it are missing from the driver, this results in not
populating all the DFS supported frequencies and returns incorrect
frequency when the clients request for them. Hence add the DFS
registration for QUPv3 RCGs.

Fixes: 4433594 ("clk: qcom: gcc: Add global clock controller driver for SC8180x")
