Subject: [PATCH 4/4] drm/panel-edp: Add some panels with conservative timings
These panels are used by Mediatek MT8173 Chromebooks but we can't find
the corresponding data sheets, and these panels used to work on v4.19
kernel without any specified delays.
Therefore, instead of having them use the default conservative timings,
update them with less-conservative timings from other panels of the same
vendor. The panels should still work under those timings, and we can
save some delays and suppress the warnings.
