drm/amdgpu: Port to DragonFly

* This commit does not build as it requires ttm changes from
the corresponding commit

Amdgpu driver changes:
* Builds with CONFIG_DRM_AMD_DC and CONFIG_DRM_AMD_DC_DCN1_0 defined
* Support for older GPUs (SI, CIK) is not implemented
* Several functions for display core module require msse and
mhard-float gcc flags to be set; and they require special
treatment from kernel by utilizing kernel_fpu_begin/kernel_fpu_end
functions
* It is required that tunable set amdgpu_hw_i2c=1 to work around
panic during module load
* Thunderbolt support is disabled
* Amdgpu trace infrastructure replaced by a stub

Drm changes:
* register_framebuffer is called at the later stage, after crtcs
were properly initialized
* drm_close implemented
* drm_connector_update_edid_property implemented
* Fix drm device stays locked in case of an error or module shutdown
* Imported drm gem framebuffer helper functions
* Fixed null pointer deref in the drm mmap ioctl
* Imported atomic64_inc and atomic_long_* functions from Linux
* Imported bitmap_complement function from Linux
* Imported kfifo struct from Linux
* Implemented dma fence array properly
* Imported rb_root_cached struct from Linux
* Implemented several dma fence functions

drm: Stop using an embedded struct drm_device in driver softcs

* All drm drivers use a struct drm_device record but are free to
allocate it by themselves in different ways or let the generic
drm subsystem code do it.

* This drm_device record can even be part of another data structure,
dynamically or statically allocated.

* We cannot just assume the length of a drm_device structure in the
softc memory block will be enough to store all driver private data.

* Make the drm softc the equivalent of a void* pointer and let the
upstream code behave as expected on Linux

drm/ttm: convert to unified vma offset manager

* Add TTM_BO_PRIV_FLAG_ACTIVE.

* Changes so we can use more of the linux ttm_bo_vm.c code. Fake
struct vm_fault, fake struct vm_operations_struct, and adjust
struct vm_area_struct. Also add related flags.

The VM interface to DragonFlyBSD is now (mostly) a wrapper around
the linux code.

* The linux red/black tree code uses some of the DFly RB macros.
This means that struct rb_root must be compatible. Add missing
fields. This fixes RB_REMOVE breakage due to it trying to iterate
rbh_inprog.

* Add set_need_resched() (empty)

* radeon_bo_is_reserved() is no longer applicable and has been removed,
allowing us to avoid implementintg ttm_bo_is_reserved(). Note that
linux-current does not have these functions.

* Refactor radeon_do_test_moves() so reflect the linux code a bit
better. This fixes a few error paths.

* radeon_verify_access() remains empty. We need the struct file
(which we don't have) to implement it.

* Make some adjustments to ttm_mem_type_from_pace() and other
API functions which use struct ttm_place instead of uint32_t.
This better reflects the linux code and fixes compile-time breakage
due to the partial API patch.

Make other struct ttm_place adjustments.

* bdev->dev_mapping is broken (partial API update in WIP) and is
still always NULL because ttm_bo_device_init() does not yet initialize
it (needs an argument passed from the chipset code).

* refactor ttm_bo_man_get_node() to fix compile issues.

* Completely rewrite the DragonFly API interfacing code in ttm_bo_vm.c.
Hopefully the fault code is now far, far more robust than it was before.

Add debug code to check for duplicate vm_page insertions, in case
we hit that panic again (it had problems due to bdev->dev_mapping being
NULL before that issue was tracked down).

kernel/drm: Remove CONFIG_PCI as a kernel option.

The code does not link in the absence of it and neither do we expect
systems without PCI support configured, nor does it make sense for
DRM specific stuff in particular, so just set it unconditionally.

If anything, it could be tied to NPCI being >0 (to check if
"device pci" is in the kernel), but for that it would have to
actually build/link without CONFIG_PCI in the first place.
