From: Sandeep Gundlupet Raju <sandeep.gundlupet-r...@amd.com>
Allow user to select the default DTB for FIT image when multiple
dtb's exists.
>From machine.conf or local.conf user can specify the default dtb
for FIT image as shown below.
FIT_CONF_DEFAULT_DTB = "board-default.dtb"
Also fallback to avaialable dtb when FIT_CONF_DEFAULT_DTB doesn't
exits or empty.
