<content type='text'>
Here, Adding db_size in byte to find the doorbell's
absolute offset for both 32-bit and 64-bit doorbell sizes.
So that doorbell offset will be aligned based on the doorbell
size.

v2:
- Addressed the review comment from Felix.
v3:
- Adding doorbell_size as parameter to get db absolute offset.
v4:
  Squash the two patches into one.

<title>drm/amdkfd: fix add queue process context clear without runtime enable</title>

<content type='text'>
There are cases where HSA runtime is not enabled through the
AMDKFD_IOC_RUNTIME_ENABLE call when adding queues and the MES ADD_QUEUE
API should clear the MES process context instead of SET_SHADER_DEBUGGER.
Such examples are legacy HSA runtime builds that do not support the
current exception handling and running KFD tests.

The only time ADD_QUEUE.skip_process_ctx_clear is required is for
debugger use cases where a debugged process is always runtime enabled
when adding a queue.

This patch fixes the case where the code currently passes
absolute register address and not the reg offset, which HWS
expects, when sending the PM4 packet to set/update CWSR grace
period. Additionally, cleanup the signature of
build_grace_period_packet_info function as it no longer needs
the inst parameter.
