[U-Boot] [PATCH v2 18/22] armv7: embed u-boot size within u-boot for use from SPL

[Aneesh V]

Embed the u-boot flash image size at a known offset from the
start of u-boot so that SPL can use it while loading u-boot
from a non-XIP media.

Signed-off-by: Aneesh V <aneesh at ti.com>
V2:
* Removed the linker script label '__flash_image_end' and its usage.
  Instead '_end' is used now
