[PATCH v2] media: dw9719: Add of_match table

[André Apitzsch via B4 Relay]

From: André Apitzsch <git@apitzsch.eu>

Add of_match table for "dongwoon,dw9719" and "dongwoon,dw9761"
compatible string. This fixes automatic driver loading when using a
device-tree, and if built as a module like major linux distributions do.

How about the DT bindings?

The configuration should be documented, too. See e.g. for an example
Documentation/devicetree/bindings/media/i2c/dongwoon,dw9768.yaml .

I was hoping, I could add it, when using the binding in a device tree.
I'll prepare a new version that also has a DT bindings patch.
