drm/doc: Relax fdinfo string constraints
...
The restriction about no whitespace, etc, really only applies to the
usage of strings in keys. Values can contain anything (other than
newline).

drm: Add common fdinfo helper
...
Handle a bit of the boiler-plate in a single case, and make it easier to
add some core tracked stats. This also ensures consistent behavior
across drivers for standardised fields.
v2: Update drm-usage-stats.rst, 64b client-id, rename drm_show_fdinfo
v3: Rebase on drm-misc-next

That section should still be inside "DRM client usage stats" rather than

drm: Document fdinfo format specification
...
Proposal to standardise the fdinfo text format as optionally output by DRM
drivers.
Idea is that a simple but, well defined, spec will enable generic
userspace tools to be written while at the same time avoiding a more heavy
handed approach of adding a mid-layer to DRM.
i915 implements a subset of the spec, everything apart from the memory
stats currently, and a matching intel_gpu_top tool exists.
Open is to see if AMD can migrate to using the proposed GPU utilisation
key-value pairs, or if they are not workable to see whether to go
vendor specific, or if a standardised alternative can be found which is
workable for both drivers.
Same for the memory utilisation key-value pairs proposal.
v2:
* Update for removal of name and pid.
v3:
* 'Drm-driver' tag will be obtained from struct drm_driver.name. (Daniel)
v4:
* Added drm-engine-capacity- tag.
