drm/msm/dp: Enable support for eDP v1.4+ link rates table
The MSM DRM driver currently does not support panels which report their
supported link rates via the SUPPORTED_LINK_RATES table.
For panels which do not offer the optional eDP v1.3 fallback via
MAX_LINK_RATE, this will cause a panel probe failure (e.g. Samsung
ATNA30DW01-1 as found in Microsoft Surface Pro 11).
Detect eDP v1.4 panels and parse the SUPPORTED_LINK_RATES table when
present.
Additionally, set the rate using LINK_RATE_SET instead of LINK_BW_SET,
but only if LINK_BW_SET hasn't already been written to.
