struct acpi_device fields are only available when CONFIG_ACPI is set. We may find use for dev_name(&adev->dev) in generic code that is build also without CONFIG_ACPI is set but currently this requires #ifdef CONFIG_ACPI churn. Provide here an accessor that returns dev_name of embedded struct device dev in struct acpi_device or NULL depending on CONFIG_ACPI setting.
