Subject: [PATCH RESEND 4/7] clk: qcom: ipq5332: drop the
 CLK_SET_RATE_PARENT flag from GPLL clocks

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.

Fixes: 3d89d52970fd ("clk: qcom: add Global Clock controller (GCC) driver for IPQ5332 SoC")
