Gabor Juhos d6cb5215a9 ar71xx: WNR2200: fix mounting root fs problem 
Solves ticket #14356 <https://dev.openwrt.org/ticket/14356>

Without this patch, UART output will show only 4 partitions:
  [    0.740000] 4 cmdlinepart partitions found on MTD device spi0.0
  [    0.750000] Creating 4 MTD partitions on "spi0.0":
  [    0.750000] 0x000000000000-0x000000050000 : "u-boot"
  [    0.760000] 0x000000050000-0x000000070000 : "u-boot-env"
  [    0.770000] 0x000000070000-0x0000007f0000 : "firmware"
  [    0.790000] 0x0000007f0000-0x000000800000 : "art"
and then linux complains :VFS: Cannot open root device "(null)"

With this patch, UART out will show 7 partitions:
  [    0.740000] 4 cmdlinepart partitions found on MTD device spi0.0
  [    0.750000] Creating 4 MTD partitions on "spi0.0":

  [    0.780000] 2 netgear-fw partitions found on MTD device firmware
  [    0.780000] 0x000000050000-0x00000014b440 : "kernel"
  [    0.790000] mtd: partition "kernel" must either start or end on erase block boundary or be smaller than an erase block -- forcing read-only

  [    0.810000] mtd: partition "rootfs" must either start or end on erase block boundary or be smaller than an erase block -- forcing read-only
  [    0.820000] mtd: device 4 (rootfs) set to be root filesystem
  [    0.830000] 1 squashfs-split partitions found on MTD device rootfs

  [    0.840000] 0x0000007f0000-0x000000800000 : "art"
