pinctrl: meson: meson8: fix the GPIO function for the GPIOAO pins 

The GPIOAO pins (as well as the two exotic GPIO_BSD_EN and GPIO_TEST_N)
only belong to the pin controller in the AO domain. With the current
definition these pins cannot be referred to in .dts files as group
(which is possible on GXBB and GXL for example).

Add a separate "gpio_aobus" function to fix the mapping between the pin
controller and the GPIO pins in the AO domain. This is similar to how
the GXBB and GXL drivers implement this functionality.

Fixes: 9dab1868ec ("pinctrl: amlogic: Make driver independent from two-domain configuration")
