ipq806x: add support for Extreme Networks AP3935

Extreme Networks AP3935i/e -
https://www.extremenetworks.com/support/documentation/access-points-ap3935i-e/

SoC: IPQ8068 QYY AT46279K45060I
RAM: NANYA 1527 NT5CC256M16DP-DI 515073W0EF 7 TW
FLASH: NOR - S25FL256S1 - 32MB
       NAND - Macronix MX30UF4G28AB - 512MB
LAN: Atheros AR8035-A J5150WL 1515 CN - RGMII
LAN2: Atheros AR8033-AL1A SKCSR.AJ1 1444 China - SGMII
WLAN2: QCA9990 OVV FNPV209 K451406
WLAN5: QCA9990 OVV FNPV209 K451406
SERIAL: RS232 Port (115200 8n1) Cisco console cable and
        4pin Serial Header | 3.3 | GND | RX | TX

MAC address for LAN1/LAN2/WLAN 2G/WLAN 5G in uboot env

 * Installation via either RJ45 console or on-board 4 PIN header

Install Method
--------------
1) Setup TFTP server, and place
     openwrt-ipq806x-generic-extreme_ap3935-initramfs-uImage image
     in /srv/tftp or similar
2) Connect to console on router and connect ethernet port "LAN1" to
     your LAN
3) Interupt the boot with any character
4) Login with admin/new2day for default password
     (use reset/FactoryDefault if password needs to be reset)
5) Set serverip to TFTP IP: set serverip 192.168.1.2
6) Set ipaddr to another IP: set ipaddr 192.168.1.101
7) Make uboot ping something to activate eth0 on boot:
     set bootcmd 'ping 192.168.1.1; run boot_flash'
     saveenv
8) TFTP image to RAM:
     tftpboot 0x42000000
openwrt-ipq806x-generic-extreme_ap3935i-initramfs-uImage
9) Boot image: bootm 0x42000000
     In OpenWRT, "LAN1" is LAN, "LAN2" is WAN
10) SFTP openwrt-ipq806x-generic-extreme_ap3935-squashfs-nand-sysupgrade.bin
     image to /tmp
11) sysupgrade /tmp/openwrt-*-nand-sysupgrade.bin
