drm/panel-simple: Add nt36672a Tianma FHD+ panel

This adds support for nt36672a Tianma FHD+ (2520x1080)
video mode panel as found on Sony Xperia 10 Plus (mermaid)
devices.

Due to the nature of phone manufacturing, it is impossible
to retrieve the actual panel name, hence the replacement
one, detailing the device it's used on.
