ramips: add support for Belkin F9K1109v1

Device specification:
- SoC: Ralink RT3883 (MIPS 74Kc) 500Mhz
- RAM: 64Mb
- Flash: 8MB (SPI-NOR)
- Ethernet: 10/100/1000 Mbps
- WLAN
	Wireless 1: SoC-integrated : 2.4/5 GHz
	Wireless 2: 2.4 GHz RT3092L
- LED: 2x USB, WAN, LAN
- Key: WPS, reset
- Serial: 4-pin header, (57600,8,N,1), 3.3V TTL,
	GND, RX, TX, V - J12 marking on board
- USB ports: 2 x USB 2.0

Flashing instructions:

Option 1 (from bootloader web)
- Hold reset button on the back of router when plugging
  in power (for at-least 10 seconds after plugged in)
- Connect to a Lan port
- Set computer IP to 10.10.10.3
- Go to http://10.10.10.123 in a web browser
- Click the Browse... Button and select the
   *squashfs.sysupgrade.bin file then click APPLY

Option 2 (from the stock admin web)
- Go to firmware upgrade
- Upload the **factory** image *initramfs.bin first
- Boot into openwrt
- From Luci web in openwrt upload the *squashfs.sysupgrade.bin

[added v1 to the compatible identifier, added pciid for
the RT3092L, fixed pci unit-address, split out the F9K110X.dtsi
to prepare for a possible F9K1103 patch]
