Add binding for the LG ACX467AKM-7 4.95" 1080×1920 LCD panel that is
found on the LG Nexus 5 (hammerhead) phone. This appears to be a JDI
panel based on some Internet searches, however a specific model number
could not be found. I disassembled an old Nexus 5 with a broken
screen and the LG part number is the only model number present on the
back of the panel, so I think that is probably the best ID to use.

See patch 1 in this series for why I went with the LG model number.

It would be great if you could take this patch, plus the corresponding
change to panel-simple.c [1]

Both patches applied to drm-misc-next (will be in v5.2). Sorry for taking so
long, I had some urgent other priorities.
