clk: qcom: gcc-qcs8300: Use retention for PCIe power domains

Browse Source 
As the PCIe host controller driver does not yet support dealing with the
loss of state during suspend, use retention for relevant GDSCs.

Fix the PCIe link not surviving upon resume, and GDSC error:
  gcc_pcie_0_gdsc status stuck at 'off'
