The msm driver implements a custom dumb_map_offset callback. This
implementation acquires the msm_gem_lock, but the underlying
drm_gem_create_mmap_offset() function is already thread-safe regarding
the VMA offset manager (it acquires the mgr->vm_lock internally).
Switching to the generic drm_gem_dumb_map_offset() helper provides
several benefits:
1. Removes the unnecessary locking overhead (locking leftovers).
2. Adds a missing check to reject mapping of imported objects, which is
invalid for dumb buffers.
3. Allows for the removal of the msm_gem_dumb_map_offset() wrapper and
the msm_gem_mmap_offset() helper function.
The logic from msm_gem_mmap_offset() has been inlined into
msm_ioctl_gem_info() to maintain functionality without the separate
helper.
This addresses the TODO:

The hw clock gating register sequence consists of register value pairs
that are written to the GPU during initialisation.
The a690 hwcg sequence has two GMU registers in it that used to amount
to random writes in the GPU mapping, but since commit 188db3d7fe
("drm/msm/a6xx: Rebase GMU register offsets") they trigger a fault as
the updated offsets now lie outside the mapping. This in turn breaks
boot of machines like the Lenovo ThinkPad X13s.
Note that the updates of these GMU registers is already taken care of
properly since commit 40c297eb24 ("drm/msm/a6xx: Set GMU CGC
properties on a6xx too"), but for some reason these two entries were
left in the table.

Currently MDP5 3.x (MSM8998, SDM630 and SDM660) platforms are support
by both DPU and MDP5 drivers. Support for them in the DPU driver is
mature enough, so it's no longer sensible to keep them enabled in the
MDP5 driver. Not to mention that MSM8998 never used an MDP5 compatible
string. Drop support for the MDP5 3.x genration inside the MDP5
driver and migrate those to the DPU driver only.
Note: this will break if one uses the DT generated before v6.3 as they
had only the generic, "qcom,mdp5" compatible string for SDM630 and
SDM660. However granted that we had two LTS releases inbetween I don't
think it is an issue.

This is supposed to test for integer overflow but it is wrong and
unnecessary. The size_add()/mul() macros return SIZE_MAX when there is
an integer overflow. This code saves the SIZE_MAX to a u64 and then
tests if the result is greater than SIZE_MAX which it never will be.
Fortunately, when we try to allocate SIZE_MAX bytes the allocation
will fail. We even pass __GFP_NOWARN so the allocation fails
harmlessly and quietly.
