[U-Boot] [PATCH v2 4/5] rockchip: dts: rk3328: add rk3328-rock64.dts

[Matwey V. Kornilov <matwey.kornilov@gmail.com>]

rk3328-rock64.dts has been taken from Linux kernel commit

    cff6d1d6f88b ("arm64: dts: rockchip: enable HS200 for eMMC on rock64")

with minor modifications (drop nodes not known by rk3328.dtsi).
