ARM: meson: add support for Libre Computer aml-a311d-cc

Add support for the Libre Computer aml-a311d-cc "Alta" board:
https://libre.computer/products/aml-a311d-cc/

The Alta board has a Credit Card form factor, similar to the
the prvevious "Le Potato" card, but with the Amlogic A311D SoC,
MIPI DSI and CSI connectors. PoE header and a single USB2 Type-C
connector replacing the microUSB one for power and USB 2.0.

The board has an embedded SPI NOR flash, and EFI Capsule support
is added.

The GUID is dynamically generated for the board, to get it:
=> efidebug capsule esrt
========================================
ESRT: fw_resource_count=1
ESRT: fw_resource_count_max=1
ESRT: fw_resource_version=1
[entry 0]==============================
ESRT: fw_class=17E07D9D-4D91-53F4-8780-1D91F279C1A5
ESRT: fw_type=unknown
ESRT: fw_version=0
ESRT: lowest_supported_fw_version=0
ESRT: capsule_flags=0
ESRT: last_attempt_version=0
ESRT: last_attempt_status=success
========================================

On the host (with the aml_encrypt_g12a result binary):
$ eficapsule --guid 17E07D9D-4D91-53F4-8780-1D91F279C1A5 -i 1 u-boot.bin u-boot.cap

On the board (from USB disk containing u-boot.cap at root):
=> load usb 0:1 $kernel_addr_r u-boot.cap
=> efidebug capsule update $kernel_addr_r

The binary will then be flashed on the SPI.
