Subject: [PATCH 10/10] cleanup dtb handling to work in the supported usecases

add SHIPSDTB variable in the uboot defaults file that needs to be set to yes for
platforms like the calxeda highbank that ship a dtb in u-boot that we want to use.
if the user defines a dtbfile in /etc/sysconfig/uboot update the extlinux.conf
with an fdt entry otherwise update a fdtdir entry unless SHIPSDTB is set to yes.
