Introduce a new DRM driver for Intel GPUs

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms. The experimental support starts with Tiger Lake.
i915 will continue be the main production driver for the platforms
up to Meteor Lake and Alchemist. Then the goal is to make this Intel
Xe driver the primary driver for Lunar Lake and newer platforms.

It uses most, if not all, of the key drm concepts, in special: TTM,
drm-scheduler, drm-exec, drm-gpuvm/gpuva and others.

Signed-off-by: Dave Airlie <airlied@redhat.com>

[airlied: add an extra X86 check, fix a typo, fix drm_exec_init interface
change].

What: /sys/devices/.../hwmon/hwmon<i>/power1_max
Date: September 2023
KernelVersion: 6.5
Contact: intel-xe@lists.freedesktop.org
Description: RW. Card reactive sustained (PL1) power limit in microwatts.
The power controller will throttle the operating frequency
if the power averaged over a window (typically seconds)
exceeds this limit. A read value of 0 means that the PL1
power limit is disabled, writing 0 disables the
limit. Writing values > 0 and <= TDP will enable the power limit.
Only supported for particular Intel xe graphics platforms.
