ath79: support Mikrotik RouterBOARD 2011-UiAS-2HnD

Mikrotik RouterBOARD 2011 series are AR9344-based wired routers, with
optional 2,4GHz 802.11n 2x2:2 Wi-Fi radio, with desktop or rack-mount
capability, featuring 5 gigabit Ethernet ports and 5 fast Ethernet
ports. Different variants of the board are supported using a single
image.
Bare-bones RouterBOARD 2011LS is supported using the same image.

Specification:
- Power: 10-28V input via 5,5/2,1 DC barrel jack, or terminal block on
  some boards
- CPU: AR9344 at 600 to 750MHz (configurable)
- RAM: 128MB (64MB in budget versions) DDR2
- Flash: 128MB (64MB in budget versions) NAND flash
- Gigabit Ethernet: 5 ports via AR8327 switch (eth1 to eth5)
- Fast Ethernet: 5 ports via AR9344 built-in switch (eth6 to eth10)
- SFP: single port through AR8327 switch (SGMII at port 6) - currently
  unsuppoorted
- PoE in: passive input up to 28V at eth1
- PoE out: passive output up to 28V at eth10
- USB: optional micro-AB host port or type-A host port
- Console: optional Cisco-style RS232 console at the back of the device,
  on budget devices available as 3.3V UART via testpoints
- LCD: 2" touchscreen-equipped LCD (unsupported)

Installation:
- perform TFTP boot of initramfs image as for netinstall procedure
  typical for Mikrotik devices
- when initramfs image boots, use sysupgrade to perform final
  installation.

If upgrading from ar71xx, clean installation should be performed, as the
devices now uses yafut to handle kernel image.

TODO:
- SFP port probes over I²C but neither link status information is
  available, nor data traffic or link establishment occurs.
- Unknown connection to display and touch panel, but some documentation
  is available (seemingly connected via SPI, according to Mikrotik's
  open source code at [1])
