rS325261: Emulate the "OR reg, r/m" instruction (opcode 0BH).
Summary

The FreeBSD HDA code uses the 0xb variant of OR when accessing
device registers. Add this emulation, using the pattern of
existing OR code.

Test Plan

Run the HDA emulation patch with a FreeBSD 11.1 guest, and cat a .wav
file to /dev/dsp.
