drm/panel-simple: add AUO P238HAN01 panel entry

Timings taken from the datasheet and the display is working in DE mode,
thus the datasheet only specifies the blanking period. sync, back porch
and front porch are arbitrarily chosen.

The datasheet can be found at [1] but for reference these are the
relevant timings:

 sym  |              | min  | typ  | max  | unit |
------|--------------+------+------+------+------+
   Tv | V period     | 1094 | 1130 | 1836 | Th   |
      | V active     | 1080 | 1080 | 1080 | Th   |
      | V blanking   |   14 |   50 |  756 | Th   |
   Fv | V frequency  |   49 |   60 |   76 | Hz   |
   Th | H period     | 1000 | 1050 | 1678 | Tclk |
      | H active     |  960 |  960 |  960 | Tclk |
      | H blanking   |   40 |   90 |  718 | Tclk |
   Fh | H frequency  | 53.7 | 67.8 | 90.0 | kHz  |
 Tclk | LVDS clock   | 53.7 | 71.2 | 90.0 | MHz  |

Keep in mind that this is a dual link LVDS panel and the horizontal
timings are only for one half of the panel.
