[PATCH 2/3] 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.
