Commit 8c8f15c9d3 added increased pitch alignment requirements to handle
nv10-nv40 tiling (which must have a small number * PoT pitch). While
NV4/NV5 do have tiling, this was never supported in nouveau.
This change enables 1920x1200 resolutions since the maximum surface
pitch has to be strictly less than 8192. The current logic will align
1920*4 up to 8192 unnecessarily.
