When running make dt_binding_check, the xlnx,vcu-settings binding
triggers the following two warnings:

	'additionalProperties' is a required property

	example-0: vcu@a0041000:reg:0: [0, 2684620800, 0, 4096] is too long

Fix the binding and make the checker happy.

dt-bindings: soc: xlnx: extract xlnx, vcu-settings to separate binding 2020-12-09T18:36:33+00:00 Michael Tretter m.tretter@pengutronix.de 2020-11-09T13:48:16+00:00 a3857f89ddb05097d4cffeb3884d6e26da8a34e2 The xlnx,vcu binding comprises two adjacent register banks: The first register bank ("vcu_slcr") contains registers for setting the clocks of the vcu and controlling the performance monitors. The second bank ("logicoreip") contains the configuration settings of the video codec unit, which are set before synthesizing the bitstream. Drivers that drive the actual video codec unit need to read the registers from the logicoreip register bank for configuring the vcu firmware. As logicoreip is a too generic name for this register bank, use "vcu-settings" as a binding name, because the register bank basically provides the configuration settings of the VCU. Therefore, add the vcu-settings binding to provide a syscon interface for other drivers to read these registers. The alternative would have been to merge the two register banks of the xlnx,vcu binding into one register bank and make xlnx,vcu provide a syscon interface, but that would lead to more incompatibility than making second register bank of xlnx,vcu optional.
