Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.

Adds support for more Intel hardware:
Broxton/Apollo Lake (was is_preliminary in 4.4)
Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).

helping and a bunch of other developers for testing.

Add a port of the TTM and Radeon DRM code from Linux 3.8.13.
Includes kernel modesetting, framebuffer console and support
for newer hardware.

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.

With lots of help from kettenis@ some macppc bits from mpi@
and some ttm refcount/queue bits from FreeBSD.

Rework how AGP memory regions are mapped and add support for AGP bridges
that do not support remapping for processor accesses.

Add new functions to map/unmap/mmap agp memory and let the agp layer
decides how these memory regions should be accessed. It's assumed here
that the bridge does not support remapping if its aperture address is 0.

This is the last diff required for having drm(4) on macppc using agp(4).

The drm_* allocation functions have been #defined to not use most of
their arguments for a while. Actually go through the code and remove the
extraneous arguments. Makes things easier to read.

make device works out if it's agp and tells the drm driver, not the
other way round. More dev->pa reduction

also remove dev->pci_vendor and dev->pci_device, and insert pci_device
into the one place any of them are needed (inteldrm's interface can give
this info to the X driver. to remove that you'd need to fix X too).

Move dev->driver over to being a pointer to a const struct, instead of stupidly
filling in a pre-allocated one on each attach.

Makes the code a bunch nicer, shrinks a kernel by about 1.5k on amd64,
helps with my sanity, and paves way for later changes.

Tested by a few for a couple of weeks now.

Rework the drm locking to be at least halfway sane. The freebsd code
held a lock over all driver ioctls in order to be ``mpsafe''. Stop lying
to ourselves for a start. This code is not fully mpsafe, and should not
pretend to be so. Put the locking around where it should, and rely on
biglock for the rest. This will need to be fixed, but avoids some of the
horrible that we have right now.

Tested by many over a long time and several iterations.

Kill some stupid agp api wrapper functions, just use the agp api
directly. While i'm here, factor out some common functionality into a

detypedef some more. No functional change.

Check the return value of agp_enable() instead of assuming it completed.

problem originally pointed out by Tobias Ulmer, thanks!

kill the stupid pci capability defines, we have our own. Don't wrap
pci_read_capability while i'm at it.

Kill some redundant ifdefs, they're taken care of elsewhere.

Apply a light paddling with the knf stick. No binary change.

Make the drm attach messages a lot prettier.

the DRM_{INFO,ERROR,DEBUG} printf macros still need some __VA_ARGS__ love.

Switch all instances of malloc/free in the DRM to drm_alloc, drm_free
and drm_calloc.

With the recent change to check overflow in drm_calloc, this means that
all allocations that require multiplication are now checked. Also use
drm_calloc() when zeroing is needed and drop the bzero/memset
afterwards. Finally, make drm_free() check for NULL, so we don't need
to do so every time.
