ipq806x: add support for ASRock G10

The ASRock G10 is a 2.4/5 GHz band 11ac "Gaming" router,
based on Qualcomm IPQ8064.

Specifications:

SoC:	Qualcomm IPQ8064
CPU:	Dual-Core A15 @ (384 - 1,400 MHz, 2C2T)
DRAM:	512 MiB (~467 MiB available)
NAND:	128 MB (Micron MT29F1G08ABBEAH4)
WLAN0:	4T4R 5 GHz Wlan (QCA9980)
WLAN1:	4T4R 2.4 GHz Wlan (QCA9980)
ETH:    5x 10/100/1000 Mbps Ethernet (QCA8337)
INPUT:  Reset Button, WPS 2.4G and WPS 5G Button
LEDS:   1 multicolor status LED
USB:    2x USB 3.0 Type-A
POWER:  12VDC/3A AC Adapter + dedicated Power Switch
UART:   Setting is 115200-8-N-1. 1x4 .1" unpopulated header
	on the PCB (J6 - very tiny silkscreen next to TX).
        Pinout: 1. 3v3 (Square - best skipped!), 2. RX, 3. GND, 4. TX

WARNING: The serial port needs a TTL/RS-232 3.3v level converter!
	 (Depending on the serial adapter RX and TX might need to
	  be swapped).

Note about the IR-Remote:
There's a 8-Bit MCU (SONIX SN8F25E21SG) which is controlling the
IR-Remote and is fed by the IR-Photodiode. The SoC can talk to
the device via I2C. The vendor's GPL archive comes with the source
of the interface driver for this as a (character driver), the main
control software is however a blob.

Installation Instructions:
 1. Download factory image to disk
 2. Apply factory image via stock web-gui

Back to stock:
 1. Login to router via ssh
 2. run "asrock_g10_back_to_factory" script from /sbin

Notes:
 - If something goes wrong durring sysupgrade, router will go back to
   factory image.
 - Asrock G10 uses partition layout from smem. So partition layout can
   be normal or alternate.
 - 900-arm-add-cmdline-override.patch was copied from 102-powerpc-add-cmdline-override.patch
   from powerpc target.

Knowledge about BOOTCONFIG partition was based on user "jmomo" post from old
OpenWrt forum (Post #50):

[bump to 5.4, add factory image, fix sysupgrade, convert partition
layout to smem, remove ipq-wifi-asrock-g10 and use ART, minor fixes]
