[PATCH v2 1/5] media: dt-bindings: add rockchip rk3576 vicap

[Amin Gattout]

Add the compatible for the Video Capture (VICAP) unit of the Rockchip
RK3576. This variant features five MIPI CSI-2 ports and a connection
to the image signal processor (ISP). The pixel clock of each MIPI port
enters the VICAP through a dedicated gate in the clock and reset unit,
so the variant takes five interface clocks and five interface resets
in addition to the aclk, hclk and dclk of the other variants.
