board: libretech-ac: move board support into dedicated directory
The libretech-ac aka aml-s805x-ac supports mainline U-boot
from a dedicated SPI flash, move the board support into
a dedicated vendor/board subdirectory in order to support
vendor specific customization.
It also aligns with the vendor downstream changes.
