MIPS: boot: Provide more uImage options
Allow more compression algorithms as well as uncompressed uImage.bin to be generated. An uncompressed image might be useful to rule out problems in the decompression code in the bootloader or even speed up the boot process at the expense of a bigger uImage file.
