Subject: [PATCH 12/13] ARM: dts: vt8500: Add VIA APC Rock/Paper board

APC Rock is a development board based on WonderMedia WM8590 released
around 2013. Paper is the same board, but with VGA port unpopulated
and shipped with a recycled cardboard case

Its hardware includes:
* Single-core Cortex-A9 CPU at 800 MHz
* 512MB DDR3 RAM
* 4GB NAND flash
* 8MB SPI NOR flash
* ARM Mali-400 GPU
* HDMI output (type A) capable of 1080p output
* VGA output (on Rock, but not on Paper)
* 2x USB 2.0 type A
* 1x USB 2.0 OTG (microUSB connector)
* microSD slot
* 10/100M Ethernet
* Combined headphones/mic via 3.5mm jack connector
* Half-height miniPCIe slot (with only USB 2.0 signals)
