ARM: dts: amlogic: meson8/8b: remove invalid pinctrl reg

The pinctrl aobus/cbus was originally here to configure the
GPIO interrupt, but it was a bad design and was moved to a
separate gpio_intc node because the GPIO interrupt is actually
separate from the pinctrl/gpio registers.

Drop this reg entry, and fix all the register offsets with a
proper range property.
