Driver for Cirrus Logic CS4281 sound chips. Originally written for NetBSD by

Tatoku Ogaito, banged into shape for OpenBSD by me. Recording has not been
tested yet, but mpg123 works fine. Sound still works after suspend/resume.

XXX: On the IBM ThinkPad X20, must disable pcibios else the cs4281 won't
generate interrupts. Cause yet unknown but probably not the driver's fault.
YMMV on other laptops with this chip.
