Initial support for Libre Computer Amlogic Boards

This MR adds support for two Amlogic SBCs from Libre Computer; AML-S905X-CC (aka. lepotato) and AML-S805X-AC (aka. lafrite).

This MR supplies its own U-Boot for lafrite, which boots from SPI by default. To make use of this U-Boot instead of the one on the SPI you need to wipe it:

# flashrom -p linux_mtd -E # erase SPI flash

Ideally since lafrite has SPI flash we should use it to flash U-Boot there.

This MR is confirmed to work on both lepotato and lafrite. Marking as ready and hoping that the CI will finish successfully.

Now thinking about this; most of the Amlogic U-Boot packages are just copy-pasted from others, but I think we should instead merge them all together into SoC-specific packages rather than device-specific packages. The only thing that differs is how you sign the U-Boot binary and how you include the blobs, and this only differs depending on the SoC, not the device. And while in the LibreELEC repo there are different blob revisions for different devices I think we can get away with using the latest revision of these blobs and optionally also build BL31 from upstream Arm Trusted Firmware-A.

Thoughts?

make a device package for p* since a lot of amlogic device is a fork of p*

You can get some inspiration from !4221 (closed)

Could also get some inspiration for flashing a U-Boot into the SPI flash, on librecomputer-lafrite. For now it's unused.

But this will go in a later MR.

@funderscore We (Libre Computer) use different bl2/bl30 than standard copy and pasted ones.

Ah, if I remember correctly you told me that the binaries in the LibreELEC repos were quite out-of-date.
