[U-Boot] [PATCH 4/6] Fix off-by-one error in passing initrd end address via device tree

[Grant Likely <grant.likely@secretlab.ca>]

From: Grant Likely <grant.likely@linaro.org>

The initrd_end variable contains the address immediately *after* the
initrd blob, not the last address containing data.  This patch fixes
an inadvertent off-by-one when setting up the initrd reserved map.
