6.17-stable review patch. If anyone has any objections, please let me know.

commit a66dabcd2cb8389fd73cab8896fd727fa2ea8d8b upstream.
HSI1/2 PCIe and HSI0 USBDP debug outputs are fixed divide-by-8. OTP also uses 1/8 from oscclk. Replace incorrect div clocks with fixed-factor clocks to reflect hardware.
