AMD SB700 boards: Set Azalia configuration flags
The existing code for setting Azalia configuration assumes that the configuration bits are contiguous within a single byte and can be set using a byte copy addressed into the lowest 2-bit subfield. The fix in Family 14 defines a union that can be addressed as a byte to overlay the bit fields. Since the offset of the four subfields is not necessarily fixed, change the code to initialize each of the four subfields individually.
