acpi: Reserve hardware ID for custom AMD ACP driver

AMD Audio CoProcessor handles I2S audio on AMD SoC's. Prior to AMD
Ryzen platforms (e.g. STONEY) it is located on the Integrated GFX
device. As the proprietary AMD driver does not support accessing this
easily, reserve a custom ACPI ID from the coreboot namespace so that
another driver can be attached in Windows device manager.
