ar71xx: generate recovery image for WNDR4300
Extended the Makefile to generate a working factory reset image
for Netgear WNDR4300. The image uses UBI with two volumes squashfs
(rootfs) and JFFS2 (rootfs_data). In order to make stock U-Boot
happy, a fake rootfs image is placed into the last erase block
of the kernel partition.

[juhosg:
- restore the NetgearNAND/initramfs macro,
- remove unused {Squash,Ubi}fsTemplate macros,
- remove board specific mtd options from CONFIG_CMDLINE, append the
board specific ubi.mtd parameter to the kernel command line instead,
- increase kernel partition size to 2MiB,
- use board specific ini file for ubinize,
- put jffs2 eof mark into the rootfs_data ubi volume,
- use KDIR_TMP for temporary images,
- use the squashfs-raw image,
- increase kernel partition size to 2MiB,
- use a local ubinize macro,
- fix macro parameter comments,
- put the fake rootfs into the last erase block of the kernel
partition,
- move Image/Build/NetgearNAND/buildkernel macro before
define Image/Build/NetgearNAND,
- don't use the wndr3700 utility, use '-M' parameter of mkimage to set
the uImage magic,
- use '-recovery' suffix for the generated image, it is only usable via
the fw_recovery function of the bootloader,
- update commit log]
