RK3228 Only GPLL and CPLL, GPLL is a common clock, does not allow dclk_vop to change its frequency, CPLL is used by GMAC, if dclk_vop use CLK_SET_RATE_PARENT and CLK_SET_RATE_NO_REPARENT flags will affect the GMAC function. If the client application does not use GMAC and CPLL is free, make this change on the local branch.
