[6.1.y] Assertion with 7xxx dGPUs

["Limonciello, Mario" <mario.limonciello@xxxxxxx>]

Hi,

In addition to the hang fix patches recently this other patch is needed 
for helping a case that ASSERT() catches.

74fa4c81aadf ("drm/amd/display: Implement workaround for writing to 
OTG_PIXEL_RATE_DIV register")

Can you please take this to stable 6.1.y too?

Thanks,
