[U-Boot] [PATCH] image: Don't relocate ramdisk to highmem

[Thierry Reding <thierry.reding@gmail.com>]

From: Thierry Reding <treding@nvidia.com>

The Linux kernel cannot unpack a ramdisk that's stored in high memory.
Unless the initrd_high environment variable is explicitly set, abide by
that restriction using the getenv_bootm_low() and getenv_bootm_mapsize()
helpers.
