bd1a9e7b11 An update for the i915 GPU driver, which brings the code up to Linux 
commit 4d93914ae3db4a897ead4b.  Some related drm infrastructure
changes are imported as needed.

Biggest update is the rewrite of the i915 gem io to more closely
follow Linux model, althought the mechanism used by FreeBSD port is
different.

49c3716bee drm: Support DRM_CAP_TIMESTAMP_MONOTONIC capability 
This fixes DPMS with KDE and radeonkms. Without this, the display would
freeze when the monitor is put into sleep state, and only resumes after
several dozens of minutes once the monitor is powered on again.

ae518d9cf4 drm: Add missing bits to drmP.h, required by the Radeon driver 
Some of the FreeBSD-specific definitions are moved to drm_os_freebsd.h.
But there's still work to do to clean it up and reduce the diff with
Linux' drmP.h.

768857b2f8 drm: Import drm_pcie_get_speed_cap_mask() in drm_pci.c 
This comes with several PCI_VENDOR_ID_* defines which should go in a
more central place.

3d85fa9250 drm: In drm_mmap_single, try ttm_bo_mmap_single() before drm_gem_mmap_single() 
In drivers such as the Radeon driver, the DRIVER_GEM features flag is
set but TTM is used to mmap buffer object.

d1f3b5c0e2 drm: Use driver-provided "use_msi" callback to determine if MSI is blacklisted 
For now, keep the static array for i915. But eventually, it should be
moved to a callback in the driver itself.

658534ed5a Switch vm_object lock to be a rwlock. 
* VM_OBJECT_LOCK and VM_OBJECT_UNLOCK are mapped to write operations
* VM_OBJECT_SLEEP() is introduced as a general purpose primitve to
  get a sleep operation using a VM_OBJECT_LOCK() as protection
* The approach must bear with vm_pager.h namespace pollution so many
  files require including directly rwlock.h

On systems with HZ=100 it caused Intel eDP video output initialization
