ipq40xx: add support for ASUS RT-ACRH17/RT-AC42U

SOC: IPQ4019 CPU: Quad-core ARMv7 Processor [410fc075] revision 5 (ARMv7), cr=10c5387d DRAM: 256 MB NAND: 128 MiB Macronix MX30LF1G18AC ETH: Qualcomm Atheros QCA8075 Gigabit Switch (4x LAN, 1x WAN) USB: 1x 3.0 (via Synopsys DesignWare DWC3 controller in the SoC) WLAN1: Qualcomm Atheros QCA4019 2.4GHz 802.11bgn 2x2:2 WLAN2: Qualcomm Atheros QCA9984 5GHz 802.11nac 4x4:4 INPUT: 1x WPS, 1x Reset LEDS: Status, WIFI1, WIFI2, WAN (red & blue), 4x LAN This board is very similar to the RT-ACRH13/RT-AC58U. It must be flashed with an intermediary initramfs image, the jffs2 ubi volume deleted, and then finally a sysupgrade with the final image performed.
