Added rate control support for ALS and proximity

Similarly setting <m> to proximity intr_persist sysfs
node would genere interrupt whenever proximity data falls
outside threshold limit <m> number of times.

Hi Sathya,

We might have a problem here because _period attribute should
be in seconds.
Thanks Daniel. I missed the units representation in the ABI doc. I work on creating a new ABI for representing the interrupt persistence and modify this patch to support it.

See:

thanks,
Daniel.
