drm/i915: introduce simple gemfs
Not a fully blown gemfs, just our very own tmpfs kernel mount. Doing so
moves us away from the shmemfs shm_mnt, and gives us the much needed
flexibility to do things like set our own mount options, namely huge=
which should allow us to enable the use of transparent-huge-pages for
our shmem backed objects.
v2: various improvements suggested by Joonas
v3: move gemfs instance to i915.mm and simplify now that we have
file_setup_with_mnt
v4: fallback to tmpfs shm_mnt upon failure to setup gemfs
v5: make tmpfs fallback kinder
v5: better gemfs failure message
