Update u-boot to support booting FIT images

This adds FIT support from Rick.

Two of the patches are only relevant to our out-of-tree Aspeed support,
but one was sent upstream. There is also a bugfix for a linker issue
discovered when preparing this release that was sent upstream.

Bugfix for building with bleeding edge binutils
 * Makefile: Fix linking with modern binutils (sent upstream[1])

FIT image support
 * Enable FIT image support and FDT loading for AST2400/AST2500
 * bootm: relocate ramdisk if CONFIG_SYS_BOOT_RAMDISK_HIGH set (sent
 upstream [2])
 * aspeed: remove hack loading ramdisk in memory
