Cleanup the kfd code by removing the unused old debugger
implementation.
The address watch was only ever implemented in the upstream
driver for GFXv7 (Kaveri). The user mode tools runtime using
this API was never open-sourced. Work on the old debugger
prototype that used this API has been discontinued years ago.
Only a small piece of resetting wavefronts is kept and
is moved to kfd_device_queue_manager.c.

PASID is defined as a few different types in iommu including "int",
"u32", and "unsigned int". To be consistent and to match with uapi
definitions, define PASID and its variations (e.g. max PASID) as "u32".
"u32" is also shorter and a little more explicit than "unsigned int".
No PASID type change in uapi although it defines PASID as __u64 in
some places.

v3: Align with existed thunk, don't change the way of raven, only renoir

v4: don't update global ignore_crat in the driver, and revise fallback
