The WiFi firmware requires that the power is kept enabled while in
suspend mode. Add the keep-power-in-suspend property in the SDIO node
to specify that the power must be kept when entering in a system wide
suspend state.

According the datasheets, emmc v2 chips (gxbb and gxl) don't support
more that 100Mhz in UHS-1 SD modes and HS in SDIO.
Align the max-frequency to 100MHz for UHS-1 and 50MHz for HS

Commit 89a5e15bcb ("gpio/mmc/of: Respect polarity in the device tree")
changed the behavior of "cd-inverted" to follow the device tree bindings
specification:
According to SDHCI standard, CD lines are specified as "active low".
Using the "cd-inverted" property means that the CD line is "active high".
Fix the SD card description for meson by setting the cd-gpios as
"active low", according to the boards specifications, and dropping the
"cd-inverted" property.

Like LibreTech-CC, the USB0 needs the 5V regulator to be enabled to power the
devices on the P212 Reference Design based boards.

All boards based on the P212 reference design (the P212 reference board
itself and the Khadas VIM) have USB connectors (in case of the Khadas
VIM the first port is exposed through the USB Type-C connector, the
second port is connected to a 4-port USB hub).
This enables the USB controller on these boards to make the USB ports
actually usable.

Extend configuring the MAC address from u-boot to all meson boards.
I didn't test this changeset but having checked libretech's u-boot
tree I believe it should just work.

On reference boards and derivatives, the HDMI Logic is powered by an external
5V regulator.
This regulator was set by the Vendor U-Boot, add the regulator and set it always-on for now.

The Amlogic P212 reference design is used by other devices as well, such
as (for example) the Khadas VIM boards. Thus this patch adds and moves
all common entries from meson-gxl-s905x-p212.dts to a new, separate
meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the
Khadas VIM).
Support for all boards based on the P212 reference design includes:
- enabling IR support
- enabling the SAR ADC (SARADC_CH1 is connected to a resistor which
indicates the hardware revision, a similar design is found on the
Khadas VIM boards)
- all MMC controllers (which means that SDIO wifi, the SD card and the
eMMC are now supported)
- pwm_ef as dependency for the SDIO wifi modules
- uart_A which is connected to the bluetooth module (the bluetooth
module itself is not enabled yet due to missing devicetree bindings
for the Broadcom serial bluetooth devices)
- uart_AO is moved to the .dtsi (as all known devices use it as their
boot-console)
Specific to the P212 board:
- this also enables the CVBS connector (which is not available on the
Khadas VIM boards for example)
- Realtek based SDIO wifi (instead of Broadcom which most other devices
use)
