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.
