drm/msm/dpu: rework documentation comments

Unfortunately the tooling doesn't check documents placed before funciton
prototypes. Such comments frequently become outdated, miss several
params, etc. Move documentation for the functions to be placed before
the actual function body, allowing 'make W=1' to actually check these
comments and report an error.

For historical reasons a lot of symbols in the MSM DisplayPort driver
used the generic dp_ prefix. Perform a mass-rename of those symbols to
use msm_dp prefix.

Basically this is a result of the following script:

sed drivers/gpu/drm/msm/dp/* -i -e 's/\<dp_/msm_dp_/g'
sed drivers/gpu/drm/msm/dp/* -i -e 's/"msm_dp_/"dp_/g'
sed drivers/gpu/drm/msm/dp/* -i -e 's/msm_\(dp_sdp_header\|dp_sdp\)\>/\1/g'

Yes, this also results in renaming of several struct fields in addition
to renaming the structs and functions, but I think the simple solution
is better than the more complex one.

accel/ivpu: Make command queue ID allocated on XArray

Use XArray for dynamic command queue ID allocations instead of fixed
ones. This is required by upcoming changes to UAPI that will allow to
manage command queues by user space instead of having predefined number
of queues in a context.

accel/ivpu: Use xa_alloc_cyclic() instead of custom function

Remove custom ivpu_id_alloc() wrapper used for ID allocations
and replace it with standard xa_alloc_cyclic() API.

The idea behind ivpu_id_alloc() was to have monotonic IDs, so the driver
is easier to debug because same IDs are not reused all over. The same
can be achieved just by using appropriate Linux API.

accel/ivpu: Defer MMU root page table allocation

Defer root page table allocation and unify context init/fini functions.
Move allocation of the root page table from the file_priv_open function to
perform a lazy allocation approach during ivpu_bo_pin().

By doing so, we avoid the overhead of allocating page tables for simple
operations like GET_PARAM that do not require them.
Additionally, the MMU context descriptor table initialization has been
moved to the ivpu_mmu_context_map_page function.

This change streamlines the process and ensures that the descriptor table
is only initialized when it is actually needed.
Refactor init/fini functions to remove redundant code and make the context
management more straightforward.

Overall, these changes lead to a reduction in the time taken by the file
descriptor open operation, as the costly root page table allocation is now
avoided for operations that do not require it.

drm/msm/a6xx: Fix excessive stack usage

Clang-19 and above sometimes end up with multiple copies of the large
a6xx_hfi_msg_bw_table structure on the stack. The problem is that
a6xx_hfi_send_bw_table() calls a number of device specific functions to
fill the structure, but these create another copy of the structure on
the stack which gets copied to the first.

If the functions get inlined, that busts the warning limit:

drivers/gpu/drm/msm/adreno/a6xx_hfi.c:631:12: error: stack frame size (1032) exceeds limit (1024) in 'a6xx_hfi_send_bw_table' [-Werror,-Wframe-larger-than]

Fix this by kmalloc-ating struct a6xx_hfi_msg_bw_table instead of using
the stack. Also, use this opportunity to skip re-initializing this table
to optimize gpu wake up latency.

Similar to how firmware loading in Sahara involves multiple files,

drm/sched: memset() 'job' in drm_sched_job_init()

drm_sched_job_init() has no control over how users allocate struct
drm_sched_job. Unfortunately, the function can also not set some struct
members such as job->sched.

This could theoretically lead to UB by users dereferencing the struct's
pointer members too early.

It is easier to debug such issues if these pointers are initialized to
NULL, so dereferencing them causes a NULL pointer exception.
Accordingly, drm_sched_entity_init() does precisely that and initializes
its struct with memset().

Initialize parameter "job" to 0 in drm_sched_job_init().

drm/msm: Remove unneeded semicolon

./drivers/gpu/drm/msm/hdmi/hdmi_phy_8998.c:282:2-3: Unneeded semicolon

This patch removes an unneeded semicolon after a switch statement in the
pll_get_post_div function. Adding a semicolon after a switch statement is
unnecessary and can lead to confusion in the code structure.
