ath79: rework Netgear nand devices image recipe
In Netgear u-boot GPL code, nand devices uses this formula to locate the
rootfs offset.
offset = (((128 + KERNEL_SIZE) / BLOCK_SIZE) + 1) * BLOCK_SIZE;
Howerver, WNDR4500 source code incorrectly define the nand block size to
64k. In some cases, it causes u-boot can't get the correct rootfs offset,
which result in boot failure. This patch workaround it by padding kernel
size to (128k * n - 128 - 1). The additional char '\0' is used to ensure
the (128 + KERNEL_SIZE) can't be divided by the BLOCK_SIZE.
