This patch allows using drm/msm without qcom display hardware. It adds a
amd,imageon compatible, which is used instead of qcom,adreno, but does
not require a top level msm node.

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.

The msm_gpu_open() function should free "show_priv" on error or it
causes static checker warnings.

Capture the GPU state on a GPU hang and store it for later playback
via the devcoredump facility. Only one crash state is stored at a
time on the assumption that the first hang is usually the most
interesting. The existing crash state can be cleared after capturing
it and then a new one will be captured on the next hang.

Convert the existing GPU show function to use the GPU state to
dump the information rather than reading it directly from the hardware.
This will require an additional step to capture the state before
dumping it for the existing nodes but it will greatly facilitate reusing
the same code for dumping a previously captured state from a GPU hang.

It's going away.
v2: Try harder to find them all.

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).

Each of the per-generation callbacks was doing this. Lets just simplify
and move it into toplevel show() fxn.

Move the contents of msm_debugfs_cleanup() to msm_drm_uninit() to free
up the drm_driver->debugfs_cleanup callback. Also remove the
mdp_kms_funcs->debugfs_cleanup callback which has no users.

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so it's not necessary to call
drm_debugfs_remove_files(). Additionally it uses
debugfs_remove_recursive() to clean up the debugfs files, so no need
to do that.

Including all drivers. I thought about keeping small compat functions
to avoid having to change all drivers. But I really like the
drm_printer idea, so figured spreading it more widely is a good thing.
v2: Review from Chris:
- Natural argument order and better name for drm_mm_print.
- show_mm() macro in the selftest.

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/msm/msm_debugfs.c:141:5: warning: no previous prototype for 'msm_debugfs_init' [-Wmissing-prototypes]
drivers/gpu/drm/msm/msm_debugfs.c:158:6: warning: no previous prototype for 'msm_debugfs_cleanup' [-Wmissing-prototypes]
In fact, these functions are declared in
drivers/gpu/drm/msm/msm_debugfs.h.
So this patch adds missing header dependencies.
