sdimage: add support for sun50i sunxi boards

Browse Source 
Modify sdcard_image-sunxi bbclass to support both sun50i and older
SoC families. Major changes are as follows:
- update comments: disk layout info
- increase boot partition size: aarch64 unified kernels can be large
- kernel image in boot partition: replace explicit name by KERNEL_IMAGETYPE
- SPL image: replace explicit name by SPL_BINARY
- implement flexible DTB file location in boot partition
  -- e.g. by defaut sun50i u-boot looks for dtb in allwinner subdirectory
  -- follow kernel dtb naming conventions, e.g. allwinner/<board>.dtb
- copy aarch64 u-boot image to image
  -- sunxi arm boards use unified u-boot/spl image
  -- sunxi aarch64 boards use two different images
