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.

This flag is needed to add the CLK_SET_RATE_PARENT flag on the gmac_tx
clock on the JH7100, which in turn is needed by the dwmac-starfive
driver to set the clock properly for 1000, 100 and 10 Mbps links.
This change was mostly made using coccinelle:
@ match @
expression idx, name, nparents;

JH71X0__MUX(
-idx, name, nparents,
+idx, name, 0, nparents,
...)
