The struct counter_synapse actions_list member expects a const enum
counter_synapse_action array. This patch renames
interrupt_cnt_synapse_actionss to interrupt_cnt_synapse_actions and adds
a const qualifier to match actions_list.

Add simple IRQ or GPIO base counter. This device is used to measure
rotation speed of some agricultural devices, so no high frequency on the
counter pin is expected.
The maximal measurement frequency depends on the CPU and system load. On
the idle iMX6S I was able to measure up to 20kHz without count drops.
