[PATCH v1] drm/panel: simple: Tune timing for ET057090DHU

[PATCH v1] drm/panel: simple: Tune timing for ET057090DHU

[Francesco Dolcini]

From: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>

VESA Display Monitor Timing v1.13 has recommendations for the historical
VGA mode 640x480 60Hz. These parameters are compatible with EDT
ET057090DHU recommended timings.

Use VESA DMT timing parameters for EDT ET057090DHU panel.
