clk: qcom: qcm2290: Set POLL_CFG_GDSCR flag for DISPCC and GPUCC GDSCs
The Qualcomm QCM2290 SoC GDSCR status bit may not reflect the actual state
of the GDSC, instead the power on/off bits in CFG_GDSCR must be polled to
determine the GDSC state correctly. Set POLL_CFG_GDSCR flag for the QCM2290
MDSS GDSC and GPUCC GX GDSC to ensure the correct GDSC status. This is not
applicable for GPUCC CX GDSC, which relies on gds_hw_ctrl status.
