This will prevent any more missing `#include "config.h"` bug, at the
cost of having to recompile some files that didn't need to be when
changing build options.

In case of a kernel that is new enough to support multiple submit-
queues, but with an adreno generation which doesn't support multiple
prioritized ringbuffers, we'd attempt to open a submit-queue with
prio=1 (medium), which is rejected by the kernel.
This could happen either w/ an older mesa (which uses fd_pipe_new())
or a newer mesa which defaults to prio=1 if no pipe context priority
flags are set.
The simple answer to fix both cases is to clamp the requested priority
according to the number of rings. This might not do exactly what you
want, if we hypothetically had 2 rings (it would result in requested
medium priority being high priority instead of low priority). But the
number of rings (for hw gen's that support this) is purely a software
construct, so the easy answer there is to have the kernel advertise at
least 3 rings if it supports more than one. There isn't really any
reason to do otherwise.

With a new-enough kernel to support prioritized submit-queues, we can
expose priority level support to mesa. Open a submit queue associated
with the fd_pipe and pass it's id back to SUBMIT ioctl.

They are less and easier to track than the public ones. The macro
drm_public will be going away by the end of the series.
