Christian Lamparter 2271967f57 apm821xx: utilize build ARTIFACTs 
The exported kernel dtbs can be build as artifacts.
This way, the MyBook Live's DTB is not generated twice.

While at it, give the artifacts their proper name.
For the wndr4700 use the "device-tree" partition name and
for the MyBook Live: "apollo3g.dtb" to match the mbl_boot.scr.

# Netgear used an old uboot that doesn't have FIT support.
# So we are stuck with either a full ext2/4 fs in a initrd.
# ... or we try to make the "multi" image approach to work
# for us.
#
# Sadly, the "multi" image has to consists of three
# "fixed" parts in the following "fixed" order:
# 1. The kernel which is in $@
# 2. The (fake) initrd which is in $@.fakerd
# 3. The device tree binary which is in $@.dtb
#
# Now, given that we use the function for the kernel which
# already has a initramfs image inside, we still have to
# add a "fake" initrd (which a mkimage header) in the second
# part of the legacy multi image. Since we need to put the
# device tree stuff into part 3.
