'svm_range_cpu_invalidate_pagetables'
This commit addresses a circular locking dependency in the
svm_range_cpu_invalidate_pagetables function. The function previously
held a lock while determining whether to perform an unmap or eviction
operation, which could lead to deadlocks.
Fixes the below:

v2: To resolve this issue, the allocation of the process context buffer
(`proc_ctx_bo`) has been moved from the `add_queue_mes` function to the
`pqm_create_queue` function. This change ensures that the buffer is
allocated only when the first queue for a process is created and only if
the Micro Engine Scheduler (MES) is enabled. (Felix)
v3: Fix typo s/Memory Execution Scheduler (MES)/Micro Engine Scheduler
in commit message. (Lijo)

The SUBMIT_ERROR() macro turns the error code negative. This extra '-'
operation turns it back to positive EINVAL again. The error code is
passed to ERR_PTR() and since positive values are not an IS_ERR() it
eventually will lead to an oops. Delete the '-'.

They are noops on GFX12. There is no suspend/resume all support
in firmware so the function doesn't do anything. KFD already
handles its own queues and they should already be unmapped at this
point so even if this runs, it's not doing anything.

All dce command_table_helper's shares a copy-pasted collection
of copy-pasted functions, which are: phy_id_to_atom,
clock_source_id_to_atom_phy_clk_src_id, and engine_bp_to_atom.
This patch removes the multiple copy-pasted by moving them to
the command_table_helper.c and make the command_table_helper's
calls the functions implemented by the command_table_helper.c
instead.
The changes were not tested on actual hardware. I am only able
to verify that the changes keep the code compileable and do my
best to to look repeatedly if I am not actually changing any code.
This is the version 4 of the PATCH, fixed comments about
licence in the new files and the matches From email to

command_table_helper instead of creating a dce_common
