This avoids using the deprecated drm_get_pci_dev() and load() hook
interfaces in the qxl driver.
The only tricky part is to ensure TTM debugfs initialization happens
after the debugfs root node is created, which is done by moving that
code into the debufs_init() hook.
Tested on qemu with igt and running a WM on top of X.
Changes since v1:
- Drop verification for primary minor in qxl_debugsfs_init.
Changes since V2:
- Put new header together with other debugfs headers.

They're gone since 8a357d1004 ("drm: Nerf DRM_CONTROL nodes").
Spotted while doing a full audit when revieng a similar patch from
Nicolai for radeon.
v2: Drink coffee first aka don't forget the unregister side.

The locking of release_lock was stupid; t should have been be called with
fence_lock_irq if it was legitimately used. Unfortunately it never protected
anything except the fence implementation correctly.

Final driver! \o/
This is not a proper dma_fence because the hardware may never signal
anything, so don't use dma-buf with qxl, ever.

QXL is a paravirtual graphics device used by the Spice virtual desktop
interface.
The drivers uses GEM and TTM to manage memory, the qxl hw fencing however
is quite different than normal TTM expects, we have to keep track of a number
of non-linear fence ids per bo that we need to have released by the hardware.
The releases are freed from a workqueue that wakes up and processes the
release ring.
releases are suballocated from a BO, there are 3 release categories, drawables,
surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling.
The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface
ids.
This requires a newer version of the QXL userspace driver, so shouldn't be
enabled until that has been placed into your distro of choice.

v1.1: fixup some issues in the ioctl interface with padding
v1.2: add module device table
v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq,
don't try flush release ring (broken hw), fix -modesetting.
v1.4: fbcon cpu usage reduction + suitable accel flags.
