Makefile: Add Kconfig option CONFIG_SPL_IMAGE to select the SPL binary
This patch adds the CONFIG_SPL_IMAGE option to select the SPL image that
shall be used to generate the combined SPL + U-Boot image. The default
value is the current value "spl/u-boot-spl.bin".
This patch also sets CONFIG_SPL_IMAGE to "spl/boot.bin" for AT91 targets
which use SPL NAND support (boot from NAND). For these build targets the
combined image "u-boot-with-spl.bin" is now automatically generated and
can be programmed into NAND as one single image (vs. SPL image and U-Boot
as 2 separate images).
