MIPS: start.S: use symbol __image_copy_end for U-Boot image relocation
Use the newly introduced symbol __image_copy_end as end address for
relocation of U-Boot image. This is needed for dynamic relocation added
in later patches. This patch obsoletes the symbols uboot_end and
uboot_end_data which are removed.
