Correct PAGE_MASK usage in radeon_vm_map_gart(). Linux defines
PAGE_MASK to be (~(PAGE_SIZE - 1)) where as our kernel defines it as
(PAGE_SIZE - 1). It is possible to flag a CS as wanting to use
GPU VM for cayman/aruba hardware though in practice Mesa won't
submit a CS flagged with GPU VM for these unless overriden via
RADEON_VA=true in the environment.
For Southern Islands radeons on the other hand GPU VM is required
and flagged by default.
