script: amlogic: add script to build 32bit image for meson64

PD#172587: script: add script to build 32bit image for meson64

    Use the new options:

      -c        specify defconfig with full name
      -f        specify rootfs
      -b        specify prefix or suffix of dts for the board
      -p        specify prefix of dts for the chip
      -d        make distclean
      -h        print help summary and examples
