ASoC: Intel: Use acpi_dev_present()
Use shiny new acpi_dev_present() and remove all the boilerplate to search for a particular ACPI device. No functional change. Cf. 2d12b6b381ba ("ACPI / utils: Add acpi_dev_present()"). Signed-off-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: Mark Brown <broonie@kernel.org>
