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.
