kernel: Nuke legacy FreeBSD "%r" format support.

Makes a quite a cleanup in subr_prf.c and less hits against things
like "%rip". Only one custom format remains - "%b".

drm/i915: Update to Linux 4.7.10

* Various bugfixes, including GPU-specific ones on Ironlake and more
recent hardware.
Runtime power management and atomic modesetting have been specially
improved.

* Fix Hardware hangs on Ironlake, Sandybridge, Ivybridge, Skylake and
Kabylake GPUs

* Fix various display flickering issues, including PSR, Broadwell and
Display-port specific ones

* Kabylake support is no longer considered experimental

* Color management has been added for Broadwell, Skylake, Kabylake as
well as Cherryview and Broxton GPUs. The intent is to obtain more
accurate color representation on various types of panel.

drm/i915: Update to Linux 4.4

* Broxton and Skylake support improvements

* Cherryview specific fixes

* Atomic modesetting conversion progress

* Improved validation of video modes. Some low-power chips can't
drive all DP screens and this is now detected by the driver.

* PSR and FBC improvements and bug fixes

* Workarounds for some specific HDMI monitors needing more time than
allowed by the spec to handle hot-plug events

* As usual, various fixes for little issues here and there

Lets see what breaks.

drm cleanup 18/x: Gently remove drm_core_has_AGP, DRIVER_REQUIRE_AGP

Whole AGP handling is very fuzzy currently, specially in ttm.
This however this attempt seems to work.

While there remove two unused structs: drm_magic_head, drm_waitlist.

The stucts drm_gem_mm and drm_magic_entry will require some extra
work in drm_fops.c

drm cleanup 14/x: Slightly rewrite drm debug subsystem.

Changes:
* Bring back kernel options handling through opt_drm.h that
got lost in: ba55f2f542af67c1331fd80f611891b0a29f57bc
* Explicitly disable DRM_LINUX option, breaks LINT64
* Add some DragonFly specific debug categories to ease up
the debugging, some DRM_DEBUG prints are quite noisy
* By default don't include PID number, hard on diffs
* Handle ioctl debug prints with separate debug bits
* Implement DRM_ERROR_RATELIMITED that uses krateprintf()
* Implement and use drm_err() and drm_ut_debug_printk()
note: that current implementation might lead to more
garbled text on a very frequent writes by several cpus

After this cleanup drm modules shrink a bit in size:
