scripts: add tool to create image for SPI boot on AM35xx
Booting from SPI on an AM35xx (and possibly other TI SOCs) requires
a special format:
- 32 bit image size in big-endian
- 32 bit load address in big-endian
- binary image converted from little- to big-endian
The mk-am35xx-spi-image tool converts barebox.bin to
this format.
