arm64: dts: ti: iot2050: Factor out DP related bits

There is a variant coming which does not support the Display Port. Move
all related bits into a separate dtsi so that only those variants
supporting the interface can include it.

Along that, remove a redundant clock setting from
k3-am65-iot2050-common-pg1.dtsi.
