[PATCH 3/6] Remove device tree booting dependency on CONFIG_SYS_BOOTMAPSZ

From: Grant Likely <grant.likely at linaro.org>
The previous patch makes u-boot use the full accessible size of ram as
the default boot mapped size if CONFIG_SYS_BOOTMAPSZ is not defined,
which means boot_relocate_fdt() can be changed to depend solely on
CONFIG_OF_LIBFDT.
