clk: qcom: gcc-sm8250: Use retention mode for USB GDSCs
[ Upstream commit ac1c5a03d3772b1db25e8092f771aa33f6ae2f7e ]
USB controllers on SM8250 doesn't work after coming back from suspend.
This can be fixed by keeping the USB GDSCs in retention mode so that
hardware can keep them ON and put into rentention mode once the parent
domain goes to a low power state.
