drm/amdgpu: Implement a new 64bit sequence memory driver
Developed a new driver which allocates a 64bit memory on
each request in sequence order. At the moment, user queue
fence memory is the main consumer of this seq64 driver.
v2: Worked on review comments from Christian for the following
modifications
- Move driver name from "semaphore" to "seq64"
- Remove unnecessary PT/PD mapping
- Move enable_mes check into init/fini functions.
v3: Worked on review comments from Christian
- drop enable_mes check
- use DECLARE_BITMAP for bit array
- added kerneldoc for seq64
v4: Worked on review comments from Christian
- Rename amdgpu_seq64_get name with amdgpu_seq64_alloc
v5: Worked on review comments from Christian
- Fix seq64 lockdep warning
- move fpriv->seq64_va check into amdgpu_seq64_unmap()
- make the function amdgpu_seq64_unmap() return as void.
- reserve the buffers as not interruptible.
v6: port to drm_exec (Alex)
v7: disable for now (Arun)
