Another round of resync and some added sound support.

sys/pc98/i386/machdep.c: sync with i386/i386/machdep.c
sys/pc98/conf/options.pc98: sync with i386/conf/options.i386

sys/i386/isa/sound: DMA auto initialize mode support for PC98.
contributed by: Akio Morita <amorita@bird.scphys.kyoto-u.ac.jp>

Definite 2.2 material, I believe.
