ar71xx: image: update Build/Image/Planex macro

- remove the 'kernel' and 'rootfs' partitions from the mtd layout,
 - move the .okli image into the uImage,
 - append the root squashfs directly after the kernel,
 - use the 64kraw template instead of the 64k
 - ensure that the generated images have enough erase blocks
   for JFFS2 garbage collection,

Tested on the MZK-W300NH board only.
