[U-Boot] [PATCH 5/5] ls2080ardb: Convert to distro boot

Most new systems in U-Boot these days make use of the generic "distro"
framework which allows a user to have U-Boot scan for a bootable OS
on all available media types.

This patch converts the LS2080ARDB board to use that framework instead
of booting from a hard coded flash offset.

This obviously means that we can no longer boot from said offset. Is
that a reasonable thing to do or should I put the bootm back into the
default boot command and only do distro boot if it fails?
