2.37.3
Add support for the Sony TD4353 JDI 2160x1080 display panel used in
some Sony Xperia XZ2 and XZ2 Compact smartphones. Due to the specifics
of smartphone manufacturing, it is impossible to retrieve a better name
for this panel.
This revision adds support for the default 60 Hz configuration, however
there could possibly be some room for expansion, as the display panels
used on Sony devices have historically been capable of >2x refresh rate
overclocking.

As discussed offline, can we just use 0, 1079 here? That way it's a bit
more clear that our column address is just width-1.

And 2159 here.

Just 0?

Unfortunate that 0x86f is again 2159 here, but we cannot easily
represent it.
