ipq40xx: use zImage for EX6100v2 and EX6150v2
The NETGEAR EX61500v2 and EX6150v2 U-Boot does not support booting LZMA
compressed images. Currently, they are using GZIP compressed kernels,
which results in ledd flash being available to the root and overlay
filesystems.
Using a zImage results in a smaller kernel and therefore increases
available space for rootfs and overlayfs.
Size reduced: ~1.1 MiB
