[PATCH v2 1/6] arm64: dts: rockchip: enable USB 2.0 on NanoPC-T6 LTS

[Marcin Juszkiewicz]

FriendlyELEC introduced new version of NanoPC-T6 SBC.

MiniPCIe slot got removed and USB 2.0 configuration has changed.
There are two external accessible ports and two ports on internal
header.

There is on-board USB hub which provides:
- one external connector (bottom one)
- two internal ports on pin header
- m.2 E port

Top USB 2.0 connector comes directly from SoC.
