arm64: rockchip: add dts + defconfig for RK3399-Q7 (Puma) SoM

The RK3399-Q7 (Puma) is a system-on-module featuring the Rockchip
RK3399 in a Qseven-compatible form-factor.

RK3399-Q7 features:
  * CPU: ARMv8 64bit Big-Little architecture,
    * Big: dual-core Cortex-A72
    * Little: quad-core Cortex-A53
    * IRAM: 200KB
  * DRAM: 4GB-128MB dual-channel
  * eMMC: onboard eMMC
  * SD/MMC
  * GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY
  * USB:
    * USB3.0 dual role port
    * 2x USB3.0 host, 1x USB2.0 host via onboard USB3.0 hub
  * Display: HDMI/eDP/MIPI
  * Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF)
  * NOR Flash: onboard SPI NOR
  * Companion Controller: onboard additional Cortex-M0 microcontroller
    * RTC
    * fan controller
    * CAN

This dts describes includes all required peripherals for booting and
basic functionality including eMMC, NOR, USB, Ethernet, HDMI output
(with audio), I2C buses (including the RTC and fan controller features
provided by the default companion controller firmware) and LED
definitions.
