[ Upstream commit 2303a9ca693e585a558497ad737728fec97e2b8a ]

CLK_GET_RATE_NOCACHE should only be necessary when the registers
controlling the rate of clock may change outside of CCF. On Amlogic,
it should only be the case for the hdmi pll which is directly controlled
by the display driver (WIP to fix this).

The other plls should not require this flag.
