The RTNI field is multiplied by 16 and incremented by 512 before being
used as the minimum number of pixel clock per horizontal line, hence
it is necessary to subtract those 512 bytes from htotal and then divide
the result by 16 before writing the value into the RTNI field. Fix the
calculation.

V2: Clamp the htotal to range 512...1008, so RTNI always fits the bitfield
I tried to apply this to drm-misc-fixes but the branch has not yet
been moved forward to v6.1-rc1.
Can I maybe get RB until then ?

Thank you
I've been told to go and poke the DRM git people at IRC to rebase
the fixes branch.
That would be #dri-devel on OFTC I think ?
