clk: rockchip: allow varying mux parameters for cpuclk pll-sources
Thers are only two parent PLLs that APLL and GPLL for core on the previous SoCs (RK3066/RK3188/RK3288/RK3368). Hence, we set fixed GPLL as alternate parent when core is switching freq. Since RK3399 big.LITTLE architecture, we need to select and adapt more PLLs (ALPLL/ABPLL/DPLL/GPLL) sources.
