imx8mp.dtsi includes a default port@1 node with an empty placeholder
endpoint intended for linking to a dsi bridge or panel.
HummingBoard Pulse mini-hdmi dtsi added and linked hdmi brodge to yet
another endpoint.

This duplicate endpoint can cause dsi_attach to fail.

Remove the duplicate node and link to the one defined in soc dtsi.
Further remove the unnecessary attach-bridge property.

Fixes: 2a222aa2bee9 ("arm64: dts: add description for solidrun imx8mp hummingboard variants")
