Implicit synchronisation is the default behaviour of the kernel when
rendering with an execobject. It may be disabled with
drm_intel_gem_bo_disable_implicit_sync(), and then to restore it use

Allow the caller to pass in an fd to an array of fences to control
serialisation of the execbuf in the kernel and on the GPU, and in return
allow creation of a fence fd for signaling the completion (and flushing)
of the batch. When the returned fence is signaled, all writes to the
buffers inside the batch will be complete and coherent from the cpu, or
other consumers. The return fence is a sync_file object and can be
passed to other users (such as atomic modesetting, or other drivers).

Relative to the original version, here one can provide a flags bitmask.
Currently only DRM_DEVICE_IGNORE_PCI_REVISION is supported.
Implementation detail:
If it's set, we will only parse the separate sysfs files and we won't
touch the config one. The latter awakes the device (causing delays)
which is the core reason why this API was introduced.
v2:
- Initialize revision to 0xff if it's unread.
- Change DRM_DEVICE_IGNORE_PCI_REVISION to DRM_DEVICE_GET_PCI_REVISION
- Add explicit note that drmGetDevice[s]2 does not retrieve the
revision by default.
v3:
- Correctly fold drmParsePciDeviceInfo() hunk in this patch.

Up-to recently (patch should land in 4.10) the kernel did not expose the
PCI device revision field as a separate sysfs file.
Thus one needed too parse the config file to retrieve it. This in
itself wakes up the device, which in some cases can be quite slow.
To avoid that, just check for the separate files and fall-back to the
original if kernel is not new enough.
v3: rework alongside drmGetDevice[s]2
