Russell Senior a03219ba09 apm821xx: remove unnecessary kernel padding
The allocation of LEBs to ubi volumes is handled by the sysupgrade script:

  package/base-files/files/lib/upgrade/nand.sh

and the ubimkvol and or ubirsvol command. Therefore, padding of the
kernel blob is not needed at all, so use cat instead of dd. The
BLOCKSIZE variable was only used in the dd command.  In any case, 63k
made no sense for the way BLOCKSIZE was being used.

63k (64512) does make sense for DTB_SIZE because of the offsets expected
by u-boot given extant u-boot-env variables.

Tested on Meraki MR24.

# 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.
