[PATCH v3] clk: qcom: gcc-sc8280xp: Allow PCIe GDSCs to enter retention state

[Manivannan Sadhasivam]

With the minimal system suspend support in place for the PCIe driver that
keeps the interconnect path voted, the ALWAYS_ON flag can now be dropped.

Also, the pwrsts PWRSTS_RET_ON flag should be used to allow the GDSCs to
enter the retention state when the parent domain get's turned off during
system suspend.
