Previously the only place to get the size of the display was from the
DSS's sysfs interface, making, for example, configuring overlays and doing
updates on manual displays more difficult.

How about adding the physical display size here as well? I suppose
mm is the standard unit for such things but for small displays more
accuracy might be nice.

That can be read from framebuffer's var struct. But I could add it here
also for completeness. Perhaps also some other display related info,
like capabilities.
