Summary

Everything needed for a pwm-backlight node such as the PineTab's
(inverted PWM on PD22, enable-gpios, brightness-levels) to drive the
panel backlight on the A64.

Note that the changes in ad64_padconf.c have already been reported in the following bugzilla issue: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=299368 I can close it, if this is picked up first.
