Fix that in the Amlogic DTs, while leaving the label names to have more

The ethmac node has to be configured for each board due to different
pinctrl nodes for RGMII/RMII. Thus the phy-mode should be specified at
the same place (= in the board .dts), making it easier to read the board
.dts file (because the phy-mode is stated explicitly, without requiring
developers to read all "parent" .dtsi as well).

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.

All Meson GX SoCs (GXBB, GXL and GXM) have a PWM controller within the
AO domain. When one of the board's LEDs is connected to one of the AO
PWM pins then this can be used to dim that LED (when the leds-pwm driver
is used).
Add the pwm_AO_ab to allow such devices to use the leds-pwm driver.

Without such reserved memory zones, running the following stress command :

multiple times:
Could lead to the following kernel crashes :
