apm821xx: WNDR4700: fix broken sysupgrade, factory images
prepend-dtb got extended to handle the Meraki devices too,
the problem here was that the Netgear WNDR4700 expects an
u-boot header in front of the DTB, whereas Meraki devices
don't.
Since the header was dropped, the WNDR4700's uboot started
to complain:
Bad Magic Number,it is forbidden to be written to flash!!
when flashing the factory.img since it expects an u-boot
header there.
Fixes: 5dece2d9355a ("apm821xx: switch over from DTB_SIZE to DEVICE_DTC_FLAGS")
