GPLL, NSS crypto PLL clock rates are fixed and shouldn't be scaled based
on the request from dependent clocks. Doing so will result in the
unexpected behaviour. So drop the CLK_SET_RATE_PARENT flag from the PLL
clocks.

Changes in V2:
	- Include the stable mailing list
	- Keep the CLK_SET_RATE_PARENT in UBI32 PLL, looks like these
	  PLL rates can be changed. So don't drop the flag.
