Since linux 6.5, .dts files live in vendor subdirs. Fix all
`KERNEL_DEVICETREE` definitions to contain the `allwinner` subdir as
prefix and drop code that previously added the prefix on demand.
On the other hand, drop the prefix for `BOOT_IMAGE_FILES`, which
searches the .dtb within `DEPLOY_DIR`.

Follow the same approach as in 32-bit sunxi SoC families:
- create sunxi64.inc: umbrella description for aarch64 sunxi
-- specify proper u-boot/spl image types
-- specify proper kernel image type
-- specify u-boot/kernel preferred providers
- create basic description of sun50i SoC family
-- sun50i SoC family is based on armv8
