This patch adds alternative way to specify DAI links by using ACPI names.
ACPI name here is considered to be used as an alias for device name during

What's DAI?
It comes from Digital Audio Interface, and DAI link in ALSA SoC
basically ties together platform, DAI and codec devices by name or
device tree node.
+#if IS_ENABLED(CONFIG_ACPI)
That's not necessary, because ACPI_HANDLE() is defined as false for
CONFIG_ACPI unset.
Actually problem acpi_bus_get_device() that is not available if
CONFIG_ACPI is not set. Which suggests was it even meant to be used in
drivers that are build for non ACPI systems too?
