6bfa331a6e board: amlogic: vim3: fix setup ethernet mac from efuse
Fix reading built-in ethernet MAC address from efuse

NOTE: MAC is stored in ASCII format, 1bytes = 2characters by 0 offset

if mac from efuse not valid we use meson_generate_serial_ethaddr

NOTE: remake odroid-n2.c from Neil Armstrong <narmstrong@baylibre.com>

aa3c7912cb board: amlogic: add MMC boot device detection for environment load
Detect eMMC or SD card boot on Odroid-C4/N2 and Khadas VIM3(l) boards and
report proper MMC device for the environment loading code. This allows to
automatically load and store environment variables on the FAT partition
or RAW offset of the MMC device without the need to use different
configurations on eMMC and SD card.

To use this feature with environment stored on FAT partition, one has to
specify an empty device part (i.e. ":1" for the first partition) in
CONFIG_ENV_FAT_DEVICE_AND_PART to let the code to set the device to the
value returned by mmc_get_env_dev() function.

adbff64af7 board: amlogic: vim3: add support for dynamic PCIe enable
The VIM3 on-board  MCU can mux the PCIe/USB3.0 shared differential
lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
an USB3.0 Type A connector and a M.2 Key M slot.
The PHY driving these differential lines is shared between
the USB3.0 controller and the PCIe Controller, thus only
a single controller can use it.

This adds this dynamic switching right before booting Linux
and the configuration steps in the boards documentation.

5aeecbcf81 board: amlogic: add a vim3 specific board support
The VIM3 will need a specific code to enable PCIe if enabled in the MCU,
thus add a specific board support for VIM3 & VIM3L.
