[PATCH] clk: qcom: gcc-sm6350: Fix gpll6* & gpll7 parents

[Luca Weiss]

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
