drm/amdgpu: generate doorbell index for userqueue
The userspace sends us the doorbell object and the relative doobell
index in the object to be used for the usermode queue, but the FW
expects the absolute doorbell index on the PCI BAR in the MQD. This
patch adds a function to convert this relative doorbell index to
absolute doorbell index.
V5: Fix the db object reference leak (Christian)
V6: Pin the doorbell bo in userqueue_create() function, and unpin it
in userqueue destoy (Christian)
V7: Added missing kfree for queue in error cases
Added Alex's R-B
V8: Rebase
V9: Changed the function names from gfx_v11* to mes_v11*
V10: Rebase
V11: Rebase
