arm64: dts: rockchip: add rk3328-rock64 board

The ROCK64 is a credit card size 4K60P HDR Media Board Computer using the Rockchip RK3328 Quad-Core ARM Cortex A53 64-Bit Processor and supporting up to 4GB 1600MHz LPDDR3 memory. It provides eMMC module socket, MicroSD Card slot, Pi-2 Bus, Pi-P5+ Bus, USB 3.0 and many others peripheral devices interface for makers to integrate with sensors and devices.

The devicetree currently supports basic peripherals, with more to be added later on.

Depends on rk805 pmic support landing, which hopefully will happen in the next days.

supports-{emmc, sd, sdio} aren't vaild properties. If you do want to speedup the init process and you could add no-sd and no-sdio for emmc.

num-slots is deprecated and would be cleaned from all dts for 4.14 cycle. And disable-wp is only used for SD card now.

The same comment for the following sd and sdio nodes.
