Subject: [PATCH 3/4] drm/panel-edp: Add unknown BOE panel for HP Omnibook
 X14

From: Jens Glathe <jens.glathe@...schoolsolutions.biz>

Seems to be like NV140DRM-N61 but with touch. Haven't disassembled
the lid to look.

Due to lack of information, use the delay_200_500_e200 timings like
many other BOE panels do for now.

The raw EDID of the panel is:

00 ff ff ff ff ff ff 00 09 e5 93 0c 00 00 00 00
25 21 01 04 a5 1e 13 78 03 ee 95 a3 54 4c 99 26
0f 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01
01 01 01 01 01 01 a4 57 c0 dc 80 78 78 50 30 20
f6 0c 2e bc 10 00 00 1a 6d 3a c0 dc 80 78 78 50
30 20 f6 0c 2e bc 10 00 00 1a 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02
00 0d 36 ff 0a 3c 96 0f 09 15 96 00 00 00 01 8b

There are no timings in it, sadly.
