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).
