drm: enable amdgpu module build; update radeon to use updated ttm api

drm/ttm: Update to match amdgpu driver, Linux 4.19 based

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

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 - Refactor task_struct and implement mm_struct

* Change td->td_linux_task from an embedded structure to a pointer.

* Add p->p_linux_mm to support tracking mm_struct's.

* Change the 'current' macro to test td->td_linux_task and call
a support function, linux_task_alloc(), if it is NULL.

* Implement callbacks from the main kernel for thread exit and
process exit to support functions that drop the td_linux_task and
p_linux_mm pointers.

Initialize and clear these callbacks in the module load/unload
in drm_drv.c

* Implement required support functions in linux_sched.c
