[PATCH v5 2/3] media: i2c: imx412: Assign v4l2 device subname based on compat string

[Bryan O'Donoghue]

imx412 and imx577 return the same chip-id when interrogated via i2c.
I've confirmed this myself by

Sakari suggested we should add a new compat which should be reflected in
the name of the media entity

https://patchwork.kernel.org/project/linux-media/patch/20220607134057.2427663-3-bryan.odonoghue@linaro.org/#24894500

Set up the .data parameter of of_device_id to pass a string which
we use to set the media entity name. Once done we can add in imx577 as a
compatible chips with the media names reflecting the directed compat string.

[PATCH v5 3/3] media: i2c: imx412: Add new compatible strings

[Bryan O'Donoghue]

The Sony imx577 uses the same silicon enabling reference code in the
available examples provided as the imx412.

Add in compatible strings to enable and differentiate the parts.

You have only one item, so drop the "items".
