aa090cb6ea device: acpi_name() should take a const struct device 
There's no reason to mutate the struct device when determining
the ACPI name for a device. Adjust the function pointer
signature and the respective implementations to use const
struct device.

6d5873d7f2 drivers/i2c: Add driver for rt5663 codec 
This commit adds a new driver for the RT5663 codec to use instead
of the generic i2c driver.  Since the kernel needs additional
driver-specific device properties we need a BIOS driver that can
provide those properties.

The kernel driver devicetree properties for this codec are at:
linux/Documentation/devicetree/bindings/sound/rt5663.txt

This was tested by booting and verifying the generated SSDT
contains the expected device properties in _DSD.
