arm64: dts: rockchip: Enable DP2HDMI for ROCK 5 ITX

Browse Source 
The HDMI0(Port next to Headphone Jack) is driven by DP1 on rk3588
via RA620(a dp2hdmi converter).

Add related dt nodes to enable it.

Note: ROCKCHIP_VOP2_EP_DP1 is defined as 11 in dt-binding header,
but it will trigger a dtc warning like "graph node unit address
error, expected "b"" if we use it directly after endpoint, so we
use "b" instead here.
