aml-t95z-plus: add board file (and u-boot 2024.04) for T95Z Plus Amlo…

…gic tvbox

- we've had kernel patches/DT (from chewitt) for this in meson64 for a long time, but I never sent the board
- uses blobs for the `tartiflette-s912` which is also an DDR3 S912 (VIM2's blobs are DDR4 and won't boot)
- this adds `u-boot 2024.04` support, using chewitt's DT & `000.patching_config.yaml` & a specific BOOTPATCHDIR
- this is a full board as-if it was an SBC, and expects to boot from mainline u-boot;
  - for that to work you've to wipe the eMMC and get rid of the vendor-supplied u-boot
  - if this is not what you want/need, you can use the aml tvbox "board" instead, together with Android u-boot
