Netgear R7800 switch LAN ports are numbered backwards in LuCI,
i.e. numbering is not corresponding to the actual physical port labels,
patch fixes that.

Remove the "firmware" partition definition from the DTS of R7800
to fix sysupgrade.

Commit 4645a6d3 defined CONFIG_MTD_SPLIT_UIMAGE_FW=y for ipq806x
and that causes mtd to misbehave as additional kernel and ubi
partitions are detected from inside the "firmware" partition.
  [    1.111324] 0x000001480000-0x000001880000 : "kernel"
  [    1.121005] 0x000001880000-0x000007900000 : "ubi"
  [    1.283912] 0x000007900000-0x000008000000 : "reserve"
  [    1.296407] 0x000001480000-0x000007900000 : "firmware"
  [    1.468043] no rootfs found after FIT image in "firmware"
  [    2.426860] 2 uimage-fw partitions found on MTD device firmware
  [    2.426931] 0x000001480000-0x000001880000 : "kernel"
  [    2.440420] 0x000001880000-0x000007900000 : "ubi"

Both kernel and ubi are already defined in DTS, so this duplication
leads into errors in sysupgrade:
  Writing from <stdin> to kernel ...
  ubiattach: error!: strtoul: unable to parse the number '6 mtd10'
  ubiattach: error!: bad MTD device number: "6 mtd10"

The partition is defined to same area as kernel+ubi, and is not
needed for sysupgrade anymore. Remove it to fix things.

Only tested for the R7800 but all of them should behave equal.

Fixes: FS#1617

Increase the available flash memory size in Netgear R7800
by taking into the use the unused "netgear" partition
that is located after the firmware partition.

Available flash space for kernel+rootfs+overlay increases
by 68 MB from 32 MB to 100 MB.

In a typical build, overlay space increases from 15 to 85,
increasing the package installation possibilities greatly.

Reverting to the OEM firmware is still possible, as the OEM
firmware contains logic to initialise the "netgear" partition
if its contents do not match expectations. In OEM firmware,
"netgear" contains 6 UBI sub-partitions that are defined in
/etc/netgear.cfg and initialisation is done by /etc/preinit

Tested with Openwrt master r7093-4fdc6ca31b and OEM V1.0.2.52

NEC Aterm WG2600HP is a 2.4/5 GHz band 11ac router, based on Qualcomm
IPQ8064.

Specification:

- IPQ8064 (384 - 1,400 MHz)
- 512 MB of RAM
- 32 MB of Flash (SPI)
- 4T4R 2.4/5 GHz
- 5x 10/100/1000 Mbps Ethernet
- 12x LEDs, 4x keys
- 1x USB 3.0 Type-A
- UART header on PCB
  - RX, TX, NC, GND, Vcc from power connector side
  - baudrate: 115200 bps

Flash instruction using initramfs image:
1. Connect serial cable to UART header
2. Connect power cable and turn on the router
3. When the "Press the [f] key and hit [enter] to enter failsafe mode"
message is displayed on the console, press the "f" key and Enter key
sequentially to enter the failsafe mode
4. create fw_env.config file with following contents on failsafe mode:
  /dev/mtd9 0x0 0x10000 0x10000
5. Execute following commands to add and change the environment
variables of U-Boot
  fw_setenv ipaddr "192.168.0.1"
  fw_setenv serverip "192.168.0.2"
  fw_setenv autostart "yes"
  fw_setenv bootcmd "tftpboot 0x44000000 wg2600hp-initramfs.bin;
  bootipq"
6. Set the IP address of the computer to 192.168.0.2, connect to the LAN
port of WG2600HP, and start the TFTP server on the computer
7. Rename OpenWrt initramfs image for WG2600HP to
"wg2600hp-initramfs.bin" and place it in the TFTP directory
8. Remove power cable from WG2600HP, reconnect it and restart WG2600HP
9. WG2600HP downloads initramfs image from TFTP server on the computer,
loads it and boot with initramfs image
10. On the initramfs image, execute "mtd erase firmware" to erase stock
firmware and execute sysupgrade with the sysupgrade image
11. Wait ~180 seconds to complete flashing
