[PATCH 2/3] drm/panel: Relax porches for HannStar HSD101PWW2

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

The porch maximum values for the HannStar HSD101PWW2 are unusually
small. Make them a bit larger to allow a more flexibility when
overriding the timings in device tree. Unfortunately the datasheet
doesn't list porch limits in detail, so this is a bit of guesswork.
