cpuquiet: Update averaging of nr_runnables

Doing a Exponential moving average per nr_running++/-- does not
guarantee a fixed sample rate which induces errors if there are lots of
threads being enqueued/dequeued from the rq (Linpack mt). Instead of
keeping track of the avg, the scheduler now keeps track of the integral
of nr_running and allows the readers to perform filtering on top.

Implemented a proper exponential moving average for the runnables
governor and a straight 100ms average for the balanced governor. Tweaked
the thresholds for the runnables governor to minimize latency. Also,
decreased sample_rate for the runnables governor to the absolute minimum
of 10msecs.

drivers: cpuquiet: Fix runnable gov device_busy

On device_busy, the runnable governor stops its sample timer and cancels
any queued runnable_work. However, it is possible for the cpuquiet
platform driver to call device_busy on cpuquiet_quiesence/wake_cpu calls
which can be invoked from the queued runnable_worker thread. This will
lead to the runnable_worker thread waiting infinitely on it self
finishing in cancel_work_sync.

Fix this by removing the cancel_work_sync call as it isn't necessary
because the worker doesn't requeue it self. Stopping the timer is
sufficient.

cpuquiet: Remove synchronization from runnables_work_func()

runnables_stop() can deadlock when cancel_work_sync() waits for the
work function to end and the work function blocks on the same lock
held by runnables_stop().

Removing the locks from runnables_work_func() fixes this. This should
be safe because runnables_lock protects runnables_state and
runnables_work_func() only reads runnables_state. Also, the functions
that change state to DISABLED do a cancel_work_sync() to guarantee the
work function stopped running.

cpuquiet: Updated balanced governor to use the runnable threads patch

The balanced governor now looks at the average number of runnable
threads when bringing cores online and offline. The balanced governor
parameters have also been updated to reflect a similar patch for
autohotplug.
