update drm to linux 5.10.47

hardware support changes include
inteldrm: better support for tiger lake
amdgpu: support for navi12, navi21 "sienna_cichlid", arcturus
amdgpu: support for cezanne "green sardine" ryzen 5000 apu

Thanks to the OpenBSD Foundation for sponsoring this work,
patrick@ for helping adapt rockchip drm, kettenis@ and mpi@
for uvm discussions and various testers.

update drm to linux 5.7

adds kernel support for
amdgpu: vega20, raven2, renoir, navi10, navi14
inteldrm: icelake, tigerlake

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping, patrick@ for helping adapt rockchip drm and many developers for
testing.

Cleanup <sys/kthread.h> and <sys/proc.h> includes.

Do not include <sys/kthread.h> where it is not needed and stop including
<sys/proc.h> in it.

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).

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping and a bunch of other developers for testing.
