drm/amdgpu: Enable seq64 manager and fix bugs
- 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)
