rockchip: add support for Radxa ROCK Pi E v3.0

ROCK Pi E v3.0 uses DDR4 SDRAM instead of DDR3 SDRAM used in v1.2x.

prepare new rk3328-rock-pi-e-v3.dts in u-boot which just includes
upstream rk3328-rock-pi-e.dts.

defconfig still uses
 CONFIG_DEFAULT_FDT_FILE="rockchip/rk3328-rock-pi-e.dtb"

because v3.0 and prior are compatible.
