uboot: Add support for U-Boot SPL
SPL is a first stage bootloader. On pandaboard it supercedes x-loader, and should now be used. This patch ensures that either SPL or xloader can be selected. A config variable has been added for the name of the SPL binary generated during u-boot build. For most platform it is u-boot-spl.bin but not always. It is MLO on OMAP for example.
