William Breathitt Gray 52eed361c2 counter: microchip-tcb-capture: Fix undefined counter channel state on probe 
commit c0c9c73434 upstream.

Hardware initialize of the timer counter channel does not occur on probe
thus leaving the Count in an undefined state until the first
function_write() callback is executed. Fix this by performing the proper
hardware initialization during probe.

Fixes: 106b104137 ("counter: Add microchip TCB capture counter")
