Subject: [PATCH v7 5/5] clk: qcom: gcc-sc7280: Update the .pwrsts for PCIe GDSC

Enabling PCIe GDSC retention to ensure controller and its
dependent clocks won't go down during system suspend.
Update the .pwrsts for PCIe GDSC so it only transitions
to RET in low power.

Signed-off-by: Krishna chaitanya chundru <quic_krichai@...cinc.com>

changes since v6:
	- Instead of marking as ALWAYS_ON setting .pwrsts to RET in low
	  power.
