clk: qcom: gcc-sc8180x: 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.

This fixes the link not surviving upon resume:

    nvme 0002:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
    nvme nvme0: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS read failed (134)
    nvme 0002:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
    nvme nvme0: Disabling device after reset failure: -19
