Hello everyone,

These two patches convert dw9807 bindings to json-schema and add a new
compatible string to the dw9807-vcm driver in order to support existing
ACPI firmware.

since v2:

- Send the correct patches --- v2 patches were from an old branch before v1.

since v1:

- Use stronger language in a comment related to a compatible string for
  old firmware.

- Remove extra newlines and quotes from bindings.

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

Convert the old text based dw9807-vcm chip DT bindings to json-schema.

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.
