Subject: [PATCH v4] arm64: dts: rockchip: update mipi cells for RK3399

From: Nickey Yang <nickey.yang@...k-chips.com>

We might include additional ports in derivative device trees, so the
'port' node should have an address, and the parent 'ports' node needs
/#{addres,size}-cells.

v4:
 * keep #{address,size}-cells in both 'ports' and 'port@0' nodes
 * separate from the rest of the series, since this is mostly
   independent of the driver refactoring
