This patch set converts the da7219 codec driver to use device/fwnode functions
to access properties, instead of the DT only of_* functions, allowing ACPI
to be used as well.

The DT bindings for da7219 have a device node for the main codec properties,
and a named child node (da7219_aad), which contains all of the accessory
detection related properties for the device. ACPI also supports this kind of
FW hierarchy (data only sub-nodes), but some support in the kernel needs to be
added to take make use of this in driver code.

The first patch adds functions to allow searching for a named child node of a
device, for both DT and ACPI, and the second patch updates the codec driver to
use the standard device/fwnode calls, including this new function.

These changes are based on the v4.7-rc4 kernel.

Changes in v4:
- Rebase to v4.7-rc4
- Use strcmp() in acpi_data_node_match() for matching ACPI data nodes.

Changes in v3:
- Use of_node_cmp() in device_get_named_child_node() to match DT node.

Changes in v2:
- Rebase to v4.7-rc1
- Small updates to codec patch based on previous reviewer comments

I'm fine with the first patch and the second one carries a couple of ACKs already, so do you want me to apply them both?
