The ODroid-C2 on-board USB Hub needs to to have it's reset signal set to
high level in order to be enumerated by the USB Host Controller.

But this management must be part of the currently in-development Generic
Power Sequence patch that will allow a USB Controller driver to start and stop
a power sequence associated to the USB Bus.

In the meantime, a simple USB Hog will work to enable the USB Hub.

The same Mali-450 MP3 GPU is present in the GXBB and GXL SoCs.

The node is simply added in the meson-gxbb.dtsi file.

For GXL, since a lot is shared with the GXM that has a Mali-T820 IP, this
patch adds a new meson-gxl-mali.dtsi and is included in the SoC specific
dtsi files.

The Khadas VIM series consists of two boards which are almost
identical:
They are both using the same GXL S905X SoC, 100Mbit/s ethernet
(through the SoC-internal PHY), 2GB DDR3 memory, a micro-SD card slot,
onboard eMMC, Broadcom based SDIO WIFI, 2x USB A and 1x USB Type-C (the
latter with OTG support). The red LED is driven by PWM_AO_B (which
allows dimming), while the blue LED is managed by the firmware.
The differences are:
- the VIM Pro has a 16GB eMMC module, while the VIM only has 8GB
- the VIM Pro uses an AP6255 a/b/g/n/ac WIFI module, while the VIM comes
  with an AP6212 b/g/n SDIO WIFI module
 (the Vim uses an 8GB eMMC module, while

The boards are based on Amlogic's GXL S905X P212 reference design, which
is why most of the functionality (all MMC controllers and power
sequences, IR remote input, the main UART, ADC and ethernet) is simply
inherited from meson-gxl-s905x-p212.dtsi.

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)

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).

Amlogic's own .dts specifies that the P201 board uses a RMII PHY (with
the reset GPIO being GPIOZ_14).
However our P201 board .dts simply inherits the phy-mode setting from
from meson-gx.dtsi where it defaults to RGMII mode.
Remove all ethernet settings from meson-gxbb-p20x.dtsi as it only
specifies the RGMII pins which are only valid for the P200 board.
Instead we add the ethmac node to the meson-gxbb-p201.dts and configure
the pinctrl property and the phy-mode for an RMII PHY.

An MDIO node (which would also specify the PHY) is not added since we
don't know which PHY is being used (and thus which PHY address would
have to be used).

While here also specify the phy-handle of the ethmac node to make the
