... such as Cuttlefish (Cloud Android virtual device) which has a
DRM virtio-gpu based gralloc and (sometimes) DRM virtio-gpu based
rendering (when forwarding rendering commands to the host machine
with Mesa3D in the guest and virglrenderer on the host).
After this change is submitted, changes such as aosp/1997572 can
be submitted to removed sepolicy that is currently duplicated
across device/google/cuttlefish and device/linaro/dragonboard as
well.
Adds a sysfs_gpu type (existing replicated sysfs_gpu definitions
across several devices are removed in the attached topic). The
uses of `sysfs_gpu:file` comes from Mesa using libdrm's
`drmGetDevices2()` which calls into `drmParsePciDeviceInfo()` to
get vendor id, device id, version etc.
Ignore-AOSP-First: must be submitted in internal as a topic first to
avoid having duplicate definitions of sysfs_gpu
in projects that are only available in internal
