ath79: add support for ubnt_bullet-m-ar7240 variant

Browse Source 
This adds support for the Ubiquiti Bullet M (AR7240).

Specifications:
- AR7240 SoC @ 400 MHz
- 32 MB RAM
- 8 MB SPI flash
- 1x 10/100 Mbps Ethernet, 24 Vdc PoE-in
- External antenna
- POWER/LAN green LEDs
- 4x RSSI LEDs (red, orange, green, green)
- UART (115200 8N1) on PCB

Flashing via WebUI:
  Upload the factory image via the stock firmware web UI.

  Attention: airOS firmware versions >= 5.6 have a new bootloader with
  an incompatible partition table!

  Please downgrade to <= 5.5 _before_ flashing OpenWrt!
  Refer to the device's Wiki page for further information.

Flashing via TFTP:
  Same procedure as other Ubiquiti M boards.

- Use a pointy tool (e.g., pen cap, paper clip) and keep the reset
  button on the device or on the PoE supply pressed
- Power on the device via PoE (keep reset button pressed)
- Keep pressing until LEDs flash alternatively LED1+LED3 =>
  LED2+LED4 => LED1+LED3, etc.
- Release reset button
- The device starts a TFTP server at 192.168.1.20
- Set a static IP on the computer (e.g., 192.168.1.21/24)
- Upload via tftp the factory image:
  $ tftp 192.168.1.20
  tftp> bin
  tftp> trace
  tftp> put openwrt-ath79-generic-xxxxx-ubnt_bullet-m-ar7240-squashfs-factory.bin

The "fixed-link" section of the device tree is needed to avoid errors like this:

  Generic PHY mdio.0:1f:04: Master/Slave resolution failed, maybe conflicting manual settings?

With "fixed-link", the errors go away and eth0 comes up reliably.
