[PATCH] clk: qcom: gcc-sa8775p: Use retention for USB power domains

[PATCH] clk: qcom: gcc-sa8775p: Use retention for USB power domains

[Akash Kumar]

The USB subsystem does not expect to lose its state on suspend:

  xhci-hcd xhci-hcd.1.auto: xHC error in resume, USBSTS 0x401, Reinit
  usb usb1: root hub lost power or was reset

To maintain state during suspend, the relevant GDSCs need to stay in
retention mode, like they do on other similar SoCs. Change the mode to
PWRSTS_RET_ON to fix.
