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.
