For stability issues, we want to limit the maximum resolution supported
by the MXSFB (eLCDIF) driver.
This patch adds a new property which we can use to impose such
limitation.

Add new DT bindings for new MXSFB driver that is using the
OF graph to parse the video output structure instead of
hard-coding the display properties into the MXSFB node.
The old MXSFB fbdev driver bindings are preserved in the
same file in the "Old bindings" section.
This is a backport from kernel 4.10.y.

Clean up the ad-hoc indentation in the documentation, no functional change.

The LCDIF driver fails at boot time because it cannot read display timings
from device tree. This is a fake error because the LCDIF DT node contains a
display device property which leads to the display driver that also provides
the timings.
This fake error case has been introduced by
commit 5443a75ed038 ("MLK-14283: dts: fix DE polarity for lcdif") and
commit 56412d6a83d8 ("MLK-13996: lcdif: Use DE polarity specified in DTS")
which fixed DE polarity panel differences for different boards.
This patch adds support for choosing a particular video mode from the ones
provided by the display driver, thus also fixing the DE polarity issue
initially fixed by the above mentioned 2 patches.

This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
