Drop the deprecated drmP.h header file, and trim msm_drv.h
to the relevant include files.
This resulted in a suprisingly many edits as many files relied
on headers included via msm_drv.h.
But msm_drv.h is not supposed to carry include files it do not need, so
the individual files have to include what extra they needs.

https://gitlab.freedesktop.org/drm/msm into drm-next
+ usual progress on cleanups
+ dsi vs EPROBE_DEFER fixes
+ msm8998 (snapdragon 835 support)
+ a540 gpu support (mesa support already landed)
+ dsi, dsi-phy support
+ mdp5 and dpu interconnect (bus/memory scaling) support
+ initial prep work for per-context pagetables (at least the parts that
don't have external dependencies like iommu/arm-smmu)
There is one more patch for fixing DSI cmd mode panels (part of a set of
patches to get things working on nexus5), but it would be conflicty with
1cff7440a86e04a613665803b42034 in drm-next without rebasing or back-merge,
and since it doesn't conflict with anything in msm-next, I think it best
if Sean merges that through drm-mix-fixes instead.
(In other news, I've been making some progress w/ getting efifb working
properly on sdm850 laptop without horrible hacks, and drm/msm + clk stuff
not totally falling over when bootloader enables display and things are
already running when driver probes.. but not quite ready yet, hopefully
we can post some of that for 5.4.. should help for both the sdm835 and
sdm850 laptops.)

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

Add a reference count to track how many times a particular
chunk of iova memory is pinned (mapped) in the iomu and
add msm_gem_unpin_iova to give up references.
It is important to note that msm_gem_unpin_iova replaces
msm_gem_put_iova because the new implicit behavior
that an assigned iova in a given vma is now valid for the
life of the buffer and what we are really focusing on is
the use of that iova.
For now the unmappings are lazy; once the reference counts
go to zero they *COULD* be unmapped dynamically but that
will require an outside force such as a shrinker or
mm_notifiers. For now, we're just focusing on getting
the counting right and setting ourselves up to be ready
for the future.

Use DRM_DEV_INFO/ERROR/WARN instead of dev_info/err/debug to generate
drm-formatted specific log messages so that it will be easy to
differentiate in case of multiple instances of driver.

This patch unifies the naming of DRM functions for reference counting
of struct drm_gem_object. The resulting code is more aligned with the
rest of the Linux kernel interfaces.

_minor_ is being dereferenced before it is null checked, hence there
is a potential null pointer dereference. Fix this by moving the pointer
dereference after _minor_ has been null checked.

The number and type of firmware files required differs for each
target. Instead of using a fixed struct member for each possible
firmware file use a generic list of files that should be loaded
on boot. Use some semi-target specific enums to help each target
find the appropriate firmware(s) that it needs to load.

Add some debugfs to dump out PFP and ME microcontroller state, as well
as some of the queues (MEQ and ROQ). Also add a debugfs file to trigger
a GPU reset (and reloading the firmware on next submit).
