media: dw9807-vcm: Add "dongwoon,dw9807" compatible string

There is firmware out there that uses "dongwoon,dw9807" compatible string
that never made it to upstream as-is. Add it to the driver to make it load
on such systems.

The chip also has an EEPROM part which is AT24 compatible (for reading
purposes) on a separate I²C address. Adding possible support for this in
the future is not affected by this change.
