[PATCH v2] drm/panel: add support for InnoLux N156BGE-L21 panel

[Alban Bedel <alban.bedel@avionic-design.de>]

This panel is used by the Medcom Wide and supported by the
simple-panel driver.

Signed-off-by: Alban Bedel <alban.bedel@avionic-design.de>

v2: * Added the v/hsync pulses for correctness (the panel doesn't
      really needs them)
    * Fixed the size to report the physical size in mm
