ipq40xx: add support for Qxwlan E2600AC C1 and C2

Qxwlan E2600AC C1 based on IPQ4019

Specifications:
SOC:	Qualcomm IPQ4019
DRAM:	256 MiB
FLASH:	32 MiB Winbond W25Q256
ETH:	Qualcomm QCA8075
WLAN:	5G + 5G/2.4G
	* 2T2R 2.4/5 GHz
	 - QCA4019 hw1.0 (SoC)
	* 2T2R 5 GHz
	 - QCA4019 hw1.0 (SoC)
INPUT:  Reset buutton
LED:	1x Power ,6 driven by gpio
SERIAL: UART (J5)
UUSB:	USB3.0
POWER:	1x DC jack for main power input (9-24 V)
SLOT:	Pcie (J25), sim card (J11), SD card (J51)

Flash instruction (using U-Boot CLI and tftp server):

 - Configure PC with static IP 192.168.1.10 and tftp server.
 - Rename "sysupgrade" filename to "firmware.bin" and place it in tftp
   server directory.
 - Connect PC with one of RJ45 ports, power up the board and press
   "enter" key to access U-Boot CLI.
 - Use the following command to update the device to OpenWrt: "run lfw".

Flash instruction (using U-Boot web-based recovery):

 - Configure PC with static IP 192.168.1.xxx(2-254)/24.
 - Connect PC with one of RJ45 ports, press the reset button, power up
   the board and keep button pressed for around 6-7 seconds, until LEDs
   start flashing.
 - Open your browser and enter 192.168.1.1, select "sysupgrade" image
   and click the upgrade button.
