arm64: dts: rockchip: add roc-rk3328-cc board

The roc-rk3328-cc is a credit card size single board computer using the
Rockchip RK3328 Quad-Core ARM Cortex A53 64-Bit Processor and supporting
up to 2GB 2133MHz LPDDR4 memory. It provides eMMC module socket, MicroSD
Card slot, USB 2.0/3.0, Gigabit Ethernet, HDMI/CVBS, Infrared Receiver,
SPDIF/I2S, and SPI/I2C/UART/PWM interfaces.

The devicetree currently supports basic peripherals.
