Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to

Adds support for more Intel hardware:

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).

helping and a bunch of other developers for testing.
