Subject: [PATCH 1/2] service/vi: Document unknown DisplayInfo struct members

It appears that the two members indicate whether a display has a bounded
number of layers (and if set, the second member indicates the total
number of layers).

Subject: [PATCH 2/2] service/vi: Correct initial width and height values

Based off RE, it appears that almost all display types seem to use
1920x1080 except for a few (null display, edid display).
