counter: microchip-tcb-capture: Fix undefined counter channel state on probe
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: 106b104137fd ("counter: Add microchip TCB capture counter")
