3414f41a13 clk: qcom: gcc-sm6350: Fix gpll6* & gpll7 parents
Both gpll6 and gpll7 are parented to CXO at 19.2 MHz and not to GPLL0
which runs at 600 MHz. Also gpll6_out_even should have the parent gpll6
and not gpll0.

Adjust the parents of these clocks to make Linux report the correct rate
and not absurd numbers like gpll7 at ~25 GHz or gpll6 at 24 GHz.

Corrected rates are the following:

  gpll7              807999902 Hz
  gpll6              768000000 Hz
     gpll6_out_even  384000000 Hz
  gpll0              600000000 Hz
     gpll0_out_odd   200000000 Hz
     gpll0_out_even  300000000 Hz

And because gpll6 is the parent of gcc_sdcc2_apps_clk_src (at 202 MHz)
that clock also reports the correct rate now and avoids this warning:

  [    5.984062] mmc0: Card appears overclocked; req 202000000 Hz, actual 6312499237 Hz

df04d166d1 clk: qcom: gcc-sm6350: Fix gcc_sdcc2_apps_clk_src
GPLL7 is not on by default, which causes a "gcc_sdcc2_apps_clk_src: rcg
didn't update its configuration" error when booting. Set .flags =
CLK_OPS_PARENT_ENABLE to fix the error.

a01ef02093 clk: qcom: gcc-sm6350: Update the .pwrsts for usb gdscs
The USB controllers on sm6350 do not retain the state when
the system goes into low power state and the GDSCs are
turned off.

This can be observed by the USB connection not coming back alive after
putting the device into suspend, essentially breaking USB.

Fix this by updating the .pwrsts for the USB GDSCs so they only
transition to retention state in low power.

Per Stephen, clk providers need to include clk-provider.h, so include in
this driver as well
