Yes, you may just revert the following commit babfaa9556d7 ("clk: imx: scu: add more scu clocks")

Alternatively, just commenting out the following single line also helps:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/clk/imx/clk-imx8qxp.c?h=v5.19#n172

I just found this out about two weeks ago before I went to vacation and since have to find out with NXP what
exactly the idea of this clocking/SCFW stuff is related to our hardware.

@NXP: If any of you guys could shed some light that would be much appreciated. Thanks!
