[PATCH v5.1 2/2] ARM: dts: bcm2711: Add unicam CSI nodes

[Jean-Michel Hautbois <jeanmichel.hautbois@xxxxxxxxxxxxxxxx>]

Add both MIPI CSI-2 nodes in the core bcm2711 tree. Use the 3-cells
interrupt declaration, corresponding clocks and default as disabled.

Thanks to Stefan Wahren for his guidance on how to deal with different
RPi variants.
