ASoC: da7213: Update driver to use device_property* FW functions
The driver now supports ACPI based initialisation as well as DT and old pdata methods. However the FW data handling still uses DT specific calls to read firmware data (of_property*) so for ACPI based initialisation the FW data will only be set to default values. This patch updates the FW handling to use device_property* calls instead so that both ACPI and DT are handled as expected.
