adreno_last_fence is no longer very useful since we have a handy
per-ring pointer directly to the values we need.

When we first did preemption the priority was set at submission
time. In order to be properly backwards compatible we made ring id 0
the lowest priority ring so that when a legacy app made a submission
it didn't get itself onto the highest priority ring by accident.
Now that we set the priority with submitqueues this is no longer
a concern and ordering priorities this way goes against long
standing convention in similar GPU drivers.
Declare a flag day and invert the priority algorithm so that
priority '0' is the highest priority and it descends from there.
The lowest prority ring is 'number of rings - 1' where the number
of active rings can be acquired through a parameter query of
MSM_PARAM_NR_RINGS.
This change also ensures that the legacy submitqueue id '0' will
use the next-to-lowest ring buffer by default for legacy
submissions.

In order to manage ringbuffer priority to its fullest userspace
should know how many ringbuffers it has to work with. Add a
parameter to return the number of active rings.

Remove the queued time from the profile struct and turn the submit time
into a proper timespec (tv_sec + tv_nsec). This should sync up better
with what userspace is used to seeing.

Record the GPU always on timer value at the start and end of a
submission on the ringbuffer. Since the timer runs at a constant
19.2 Mhz this is a handy way of tracking how long each
submission takes.
The timer values are recorded in the memptrs. Each ringbuffer is
given a circular list of 128 entries to store the event ticks;
this should be enough to avoid running out of room even when the
ring is completely full of submissions.
Add trace events for the user to track when submissions are
queued, submitted to the ringbuffer and retired. The submitted
trace point shows the GPU ticks and the current kernel time at
submit time (as read by the CPU) and the retired trace event shows
the GPU ticks at submission start/end as read by the GPU. Taken
together these two events can provide a pretty close match between
the current GPU time and the kernel time which is handy for tracing
tools that try to match up the various kernel events with one
another.

pagetypeinfo_showmixedcount_print is found to take a lot of time to
complete and it does this holding the zone lock and disabling interrupts.
In some cases it is found to take more than a second (On a 2.4GHz,8Gb
RAM,arm64 cpu). Avoid taking the zone lock similar to what is done by
read_page_owner, which means possibility of inaccurate results.

When an attempt is made to free an event on a CPU which is
no longer online, perf tries to bring the CPU online. This
can fail, resulting in an UP_CANCELLED notifier, which
eventually tries to acquire the ctx->mutex which is already
being held by the code, which brings up the CPU.
Removing the attempt to bring the cpu up will remove this
deadlock, but also requires temporarily removing support of
counting events across hotplug. This will be restored in a
later patch.
