- Enable the seq64 mapping sequence.
- Fix wflinfo va conflict and other bugs.

v1:
  - The seq64 area needs to be included in the AMDGPU_VA_RESERVED_SIZE
    otherwise the areas will conflict with user space allocations (Alex)

  - It needs to be mapped read only in the user VM (Alex)

v2:
  - Instead of just one define for TOP/BOTTOM
    reserved space separate them into two (Christian)

  - Fix the CPU and VA calculations and while at it
    also cleanup error handling and kerneldoc (Christian)

Some chips provide both average and input power.  Previously
we just exposed average power, add a new query for input
power.

<title>drm/amdgpu: Implement a new 64bit sequence memory driver</title>

<id>c8031019dc95e3ab7cc0b09f1894c5f52dc0c187</id>
<content type='text'>
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-&gt;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)
