aboot: improve appended device tree support
Extends the device tree by 1024 bytes to allow for extra
stuff added by the bootloader.
Copies the device tree over the tags since the tags get thrown
out if DTB is preset anyway.
Clears out the old DTB magic so if kernel turns on the
APPENDED_DTB config option, it won't find the wrong one.
