drm/amd/display: Add chip mask to HDMI retimer/redriver check

There were cases where the chip caps held additional bits that led to
the retimer/redriver check failing; use the proper mask to ensure that
we have only the bits that we care about for the check in question.

drm/amd/display: Correct timings in build scaling params

A previous patch set the addressable timing as active + border,
when in fact, the VESA standard specifies active as equal to
addressable + border.

This patch makes the fix more correct and in line with the standard.
