    ar71xx: add support for ALFA Network AP91-5G
    
    ALFA Network AP91-5G is a 5 GHz outdoor AP/CPE board, based on Atheros
    AR7240 + AR9280.
    
    Specification:
    
    - 400/400/200 MHz (CPU/DDR/AHB)
    - 32 MB of RAM (DDR1)
    - 8 MB of FLASH (SPI NOR)
    - 1x 10/100 Mbps Ethernet, with passive PoE support (24 V)
    - 1T1R 5 GHz (AR9280), with ext. PA (SE5004L) and LNA, up to 27 dBm
    - 6x LED (5 are driven by GPIO)
    - 1x button (reset)
    - external h/w watchdog (EM6324QYSP5B, disabled and not used)
    - header for optional 802.3at/af PoE module
    - DC jack for main power input (optional, not installed by default)
    - UART and LEDs headers on PCB
    
    Flash instruction:
    
    Use "factory" image in vendor GUI (in case of problems, make sure your
    board has up to date firmware). Alternatively, TFTP in U-Boot can be
    used: select option "2. Load system code then write to Flash via TFTP"
    during early boot and use "sysupgrade" image.
