When configured with 4GiB DRAM size, only 3.8GiB is available, the
I/O beeing mapped in the last 256MiB of the first 4GiB physical memory/
First fixup the mm_region to handle the first 3.8GiB as memory and the
last 256MiB as I/O.
Then limit the real memory reported by the firmware to the available
physical space, 3.8GiB aligned with the mm_region memory zone size.

Adds support for Amlogic G12A USB Device mode.
The DWC2 Controller behind the Glue can be connected to an OTG
capable PHY. The Glue setups the PHY mode.
This patch implements Device mode support by adding a board_usb_init/cleanup
setting up the DWC2 controller and switch the OTG capable port to Device
before starting the DWC2 controller in Device mode.

Add support for the Amlogic G12A SoC, which is a mix between the
new physical memory mapping of AXG and the functionnalities of
the previous Amlogic GXL/GXM SoCs.
To handle the internal ethernet PHY, the Amlogic G12A SoCs now
embeds a dedicated PLL to feed the internal PHY.
