Activate PWM pin muxing for Apalis PWM3. Note that the same PWM3 is
already active on pu6 being Apalis BKL1_PWM as well. Therefore exporting
that one for raw sysfs access will fail and one has to revert to using
the pwm backlight.

Downstream commit 668ddb921800 ("apalis-tk1: activate pwm pin muxing for
pwm3").
