ARM: dts: vf610-colibri: Add PWM support
The Colibri standard defines four pins as PWM outputs, two of them (PWM A and C) are routed to FTM instance 0 and the other two (PWM B and D) are routed to FTM instance 1. Hence enable both FTM instances for the Colibri module and mux the four pins accordingly.
