        syssrc/sys/dev/isa: ym.c ymvar.h

Log Message:
 1. Change equalizer (treble, bass) to be ``flat'' if the values set at
    the center position (128), so as to be compatible with other drivers.
    The equalizer is enhancement only, and the values < 128 don't take
    any effect.

    Yeah, this causes spec change....
    For equalization.treble and equalization.bass, the relation between
    old and new value is

        new_value = (old_value / 2) + 128.

    (Note this does not apply to equalization.surround.)

 2. Support ++ and -- of mixerctl(1) for stepping volume variables.

 3. Fix problem where the chip is not powered up
    when the mic input is unmuted.
