<title>drm: convert .debugfs_init() hook to return void.</title>

<id>urn:sha1:7ce84471e3c72e23020b046714358b45a7ffe9ab</id>
<content type='text'>
As a result of commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail) and changes to various debugfs
functions in drm/core and across various drivers, there is no need for
the drm_driver.debugfs_init() hook to have a return value. Therefore,
declare it as void.

This also includes refactoring all users of the .debugfs_init() hook to
return void across the subsystem.

v2: include changes to the hook and drivers that use it in one patch to
prevent driver breakage and enable individual successful compilation of
this change.

<id>urn:sha1:b9c82f593f26567845060df66486c56906cc6371</id>
<content type='text'>
Since 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), drm_debugfs_create_files() never
fails and should return void. Therefore, remove unnecessary check and
error handling for the return value of drm_debugfs_create_files()
in vc4_debugfs_init().

v2: remove conversion of vc4_debugfs_init() to void to enable individual
compilation and avoid build issues and breakage.

Drop use of the deprecated header drmP.h.
Fix so vc4_drv.h is now self-contained, and fixed fall-out in remaining
files.

Divided include files in blocks.
Sorted include files within their blocks.

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.

<content type='text'>
The global list of all debugfs entries for the driver was painful: the
list couldn't see into the components' structs, so each component had
its own debugs show function to find the component, then find the
regset and dump it.  The components also had to be careful to check
that they were actually registered in vc4 before dereferencing
themselves, in case they weren't probed on a particular platform.
They routinely failed at that.

Instead, we can have the components add their debugfs callbacks to a
little list in vc4 to be registered at drm_dev_register() time, which
gets vc4_debugfs.c out of the business of knowing the whole list of
components.

Thanks to this change, dsi0 (if it existed) would register its node.

v2: Rebase on hvs_underrun addition.
v3: whitespace fixup
