ARM: dts: msm: 8x26: add support for 1080p panel boards

Display panels often do not support run time detection. To support
different types of display, we need to create different boards. This
is currently being handled by using the platform subtype field in
socinfo. Create new files for the new panel and rename the old ones
accordingly in preparation for this new platform subtype.
