[roll] Roll fuchsia [amlogic-dipslay][hdmi] Do not alter the display mode.
Previously the amlogic-display driver altered the display mode
to support 4K resolutions. The driver had to keep an unaltered
display mode for comparison, but use the altered display mode to
drive the display hardware. This workaround was never used in
amlogic-provided display driver software.
This implementation doesn't work for 4K displays (see bug
fxbug.dev/124984) and it also reduces the code readability.
Now that we are not targeting 4K displays, we should be able
to remove this hack so that the display mode will be always
passed through.
Test: display-tool squares 1 on VIM3 using the following displays:
[1] MIMO display (1280x800).
[2] Google JN32A (3840x2160) with resolution fallback to 2560x1440.
[3] Acer B326 (3840x2160), with resolution fallback to 1920x1080.
[4] Dell P2720DC (2560x1440).

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
