Remove device tree booting dependency on CONFIG_SYS_BOOTMAPSZ
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. Signed-off-by: Grant Likely <grant.likely@linaro.org>
