Add the SAR ADC to meson-gxbb.dtsi and meson-gxl.dtsi. GXBB provides a
10-bit ADC while GXL and GXM provide a 12-bit ADC.
Some boards use resistor ladder buttons connected through one of the ADC
channels. On newer devices (GXL and GXM) some boards use pull-ups/downs
to change the resistance (and thus the ADC value) on one of the ADC
channels to indicate the board revision.

This adds the pwm_ao_b pin to allow boards which have an LED connected
to GPIOAO_9 to use the leds-pwm driver (by activating the pwm_AO_ab node
and passing the pwm_ao_b_pin pinctrl-reference).

This adds pinctrl group nodes for the CTS and RTS pins of each serial
controller. This makes it possible to enable the CTS and RTS pins which
are controlled by the serial controller hardware (through the meson_uart
driver).

This adds the missing node for the uart_AO_B port to the meson-gx.dtsi
(as this is supported by GXBB, GXL and GXM) along with the required
pinctrl pins. This is required as some boards are using it (the boards
from the Khadas VIM series for example have it exposed on the pin
headers).

This patch introduces the basic support for the Amlogic S905X (Meson
GXL) and for the Amlogic evaluation board P212.
No documentation has been released yet for this SoC, so for now only the
bare minimum has been added in the DT.
