drm/vmwgfx: Remove unused hugepage support 

There's no point in explicitly trying to align virtual memory to
facilitate huge page table entries or huge page memory in buffer objects
given that they're not being used.

Transparent hugepages support for vram allocations has been gradually
retired over the last two years making alignment of unmapped areas
unneeded and pointless.
