--------------------------------
[ Upstream commit 01a5e4c6731ab6b4b74822661d296f8893fc1230 ]
GPLL 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 GPLL clocks.
---- Changes in V2: - New patch
