ipq40xx: add support for 8devices Habanero DVK

This patch adds support for the 8devices Habanero development board.

Specs are:
CPU: QCA IPQ4019
RAM: DDR3L 512MB
Storage: 32MB SPI-NOR and optional Parallel SLC NAND(Some boards ship with it and some without)
WLAN1: 2.4 GHz built into IPQ4019 (802.11n) 2x2
WLAN2: 5 GHz built into IPO4019 (802.11ac Wawe-2) 2x2
Ethernet: 5x Gbit LAN (QCA 8075)
USB: 1x USB 2.0 and 1x USB 3.0 (Both built into IPQ4019)
MicroSD slot (Uses SD controller built into IPQ4019)
SDIO3.0/EMMC slot (Uses the same SD controller)
Mini PCI-E Gen 2.0 slot (Built into IPQ4019)
5x LEDs (4 GPIO controllable)
2x Pushbutton (1 is connected to GPIO, other to SoC reset)
LCD ZIF socket (Uses the LCD controller built into IPQ4019 which has no driver support)
1x UART 115200 rate on J18

2x breakout development headers
12V DC Jack for power
DIP switch for bootstrap configuration

Installation instructions:
Since boards ship with vendors fork of OpenWrt sysupgrade can be used.
