ASoC: cs35l56: Attempt to read from cirrus,speaker-id device property first

Browse Source 
When cs35l56 is connected via cs42l43 there isn't an ACPI node for the
cs35l56 so all properties are under the cs42l43 ACPI node. We're adding
a property as a way for the cs42l43 driver to pass this info in via a
software node.
