rockchip: rk3328: add rock-pi-e dts file

The ROCK-PI-E is a credit card size SBC based on Rockchip RK3328
Quad-Core ARM Cortex A53.

    Net - Dual ethernet port, 1 X Gbe, 1 X 100M
    USB - USB 3.0
    DC  - USB-Type C, 5V 2A
    Storage - TF card, eMMC

Just build idbloader.img and u-boot.itb for Rockpi E board and
follow the blow steps to replace the relevant partition.

    dd if=idbloader.img of=/dev/sdcard seek=64 conv=notrunc
    dd if=u-boot.itb of=/dev/sdcard seek=16384 conv=notrunc
