Alex Waterman 35ae4194a0 gpu: nvgpu: Add translation for NVGPU MM flags
Add a translation layer to convert from the NVGPU_AS_* flags to
to new set of NVGPU_VM_MAP_* and NVGPU_VM_AREA_ALLOC_* flags.
This allows the common MM code to not depend on the UAPI header
defined for Linux.

In addition to this change a couple of other small changes were
made:

1. Deprecate, print a warning, and ignore usage of the
   NVGPU_AS_MAP_BUFFER_FLAGS_MAPPABLE_COMPBITS flag.
2. Move the t19x IO coherence flag from the t19x UAPI header
   to the regular UAPI header.
