The width/height fields in the plane descriptors for v12 are missing
their minus(1) modifiers.
This change adds the missing modifiers, which implies also setting
default values to 1 due to how the Two-Plane YUV Overlay interacts with
the plane descriptors.
Fixes: b6d5e01120 ("pan/genxml: Add v12 definition")
