colibri imx6 dt: don't configure pwmleds
With /sys/class/pwm a more versatile interface to pwm exists now.
PWM<A>: pwmchip3 export 0
PWM<B>: pwmchip1 export 0
PWM<C>: pwmchip4 export 0
PWM<B>: pwmchip2 export 0
e.g. configure a 1kHz 25% on PWM<C>:
(period and duty cycle in nano seconds)
$ cd /sys/class/pwm/pwmchip3
$ echo 0 > export
$ echo 1000000 > pwm0/period
$ echo 250000 > pwm0/duty_cycle
$ echo 1 > pwm0/enable
