rambi: Add ACPI devices and interrupts for codec and ALS
The Codec and ALS both have interrupt sources that can be configured. The ALS kernel driver currently does not try to use it but the codec driver does for things like jack detect. ACPI Devices are added, but as with other ACPI devices the HID may need to be updated once more official strings are decided.
