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.

ARM: tegra: cpuquiet: make userspace governor actions synchronous

Userspace expects changes to happen synchronously. Implement this by waiting
with a (configureable) timeout for the action to happen.

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: Fix race in runnable governor

Fixed a race where the cpuquiet driver would call device_free() before
the governor was started, which would lead to a kernel panic because
runnables_timer was not initialized.

Introduced RUNNING state, so states are:
- DISABLED: truly disabled
- IDLE: enabled, but not polling upon request from the driver
- RUNNING: actively polling
