This patch series adds basic fdinfo support to the Panfrost DRM driver.
It will display a series of key:value pairs under /proc/pid/fdinfo/fd
for render processes that open the Panfrost DRM file.

The pairs contain basic drm gpu engine and memory region information that
can either be cat by a privileged user or accessed with IGT's gputop
utility.
