default LAN_PROD pipe is not connected on MHI config.

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.

A negative sleep time could be interpreted as a large positive sleep
time when its casted to a unsigned type. This could result in CPU sleeping
for a longer than expected duration resulting in missed interrupts.

This is required to add a PM QOS request to disallow L2PC on masked CPUS.
It improves queue to submit time for first set of GPU commands
which results in GPU wake up.

Removed a local variable in mmc_start_req() which was used to store the
error encountered while starting a new data request. If an error is
encountered while starting a new request, the error
information is stored in the mrq. The error information stored in the
mrq is during error handling. So removing the unused variable.
