drm/nouveau: use tile_mode and pte_kind for VM_BIND bo allocations
[ Upstream commit 959314c438caf1b62d787f02d54a193efda38880 ]
Allow PTE kind and tile mode on BO create with VM_BIND, and add a
GETPARAM to indicate this change. This is needed to support modifiers in
NVK and ensure correctness when dealing with the nouveau GL driver.
The userspace modifiers implementation this is for can be found here:
