Subject: [PATCH] staging:iio:trigger:bfintmr: Only enable timer when necessary

This patch hooks up the set_trigger_state callback for the blackfin timer
trigger driver and only enables the timer when a trigger consumer requests it to
be enabled. There really is no reason to keep the timer running and generate
interrupts if nobody is listening to them.
