[PATCH] arm64: dts: ti: k3-am69-sk: remove assigned-clock-parents for unused VP

[Jayesh Choudhary]

VP2 and VP3 are unused video ports and VP3 share the same parent
clock as VP1 causing issue with pixel clock setting for HDMI (VP1).
So remove the parent clocks for unused VPs.

Fixes: 6f8605fd7d11 ("arm64: dts: ti: k3-am69-sk: Add DP and HDMI support")
Reported-by: Nishanth Menon <nm at ti.com>
