Add board config for MXQ TV box

[domin144]

Description

This change introduces a config for MXQ TV box based on S805 chip. This revives the s805_autoscript file, which is being sought for by the factory boot loader, making it possible to boot from SD card.

How Has This Been Tested?

I built an image with:

./compile.sh build BOARD=aml-s805-mxq BRANCH=edge BUILD_DESKTOP=yes BUILD_MINIMAL=no DESKTOP_APPGROUPS_SELECTED='browsers internet multimedia' DESKTOP_ENVIRONMENT=xfce DESKTOP_ENVIRONMENT_CONFIG_NAME=config_base KERNEL_CONFIGURE=no RELEASE=bookworm

I flashed an image on an SD card and booted the board. I was able to run xserver with display connected on integrated HDMI port and use mouse and keyboard connected to USB ports. Ethernet connection was working too.

Notice

This is my first PR to this project, so any advice is appreciated. The board support and testing is not of high quality, but should not affect any other board and give good starting point for further work. Prior to these changes running armbian on the MXQ board requires non-trivial, manual adjustments to the image.

Check if you can make use of existing boot scripts.

Rename to:
function post_family_tweaks__aml_s805_logo() {

And does logo shows?

[domin144]

I don't recall seeing the logo. I don't install the image to builtin memory. I rely on the factory intalled u-boot to load armbian from SD card. That's why some content of the boot partition are unused, at least for now. This fragment is left over after starting from other board's config.
I will remove it.

I am away from home and have no access to the test device. I will update and test, but it will be sometime in January.

I will remove it.

OK, it probably doesn't work.

but it will be sometime in January.

No worries.

Odroid-c1 and onecloud are the closest boards, but neither script will work out of the box due to hard-coded dtb path. I could try to extend one of those scripts, but this is additional risk of breaking those boards (I have no access to those boards to test). I think it should better be done under a separate PR.
