Xingyu Wu 538d5477b2 clk: starfive: jh7110-sys: Add notifier for PLL0 clock
Add notifier function for PLL0 clock. In the function, the cpu_root clock
should be operated by saving its current parent and setting a new safe
parent (osc clock) before setting the PLL0 clock rate. After setting PLL0
rate, it should be switched back to the original parent clock.
