Subject: [PATCH] drm/panel: update innolux n116bge timings

There are several different models of N116BGE.  According to the commit
that added innolux_n116bge_mode [0], this N116BGE is for the eDP variety.

   drm/panel: simple: Add Innolux N116BGE panel support

The clock and htotal values from add by that patch are out of spec according to
the datasheets I have seen for the eDP N116BGE (-EA2 and -EB2).

This patch changes the values to the "Typ" values on the datasheet.

Thierry,

It is possible that your timings were correct for the panel you are using on
the norrin reference board.  In that case I'm happy to upload a new patch
that creates a new panel entry.  However, I'm pretty sure we are using the
same N116BGE.
