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.
