Second version of patch-set that adds support for EDT ETM043080DH6-GP. This
is a 480x272 TFT Display with capacitive touchscreen and it is compatible
with the simple panel driver.
We have tested it with our iWave-G22D Generic SODIMM Development Board.
In v2, after Sam Ravnborg's review, I've rebased the patches against
drm-misc-next and modified the proper bindings file for the simple panels.
I have also added the mandatory connector-type field and corrected the bus
type as it is a 18bbp, therefore an RGB666.
Unfortunately, we do not have access to the datasheet, therefore we could
not use the display_timings format.

Applied to drm-misc-next and pushed out.
Note: Will hit next merge window, as it is too late for the current merge window.
