Log Message:
Raise spl4 to spl6 in quick_go--I am now experimenting with interrupts
at levels 5 (sound) and 6 (via1) on the Q700.
Raise splhigh when reading and writing registers.  It's ugly, but it's
possible that we could get an interrupt from a higher-level source,
causing a re-read of a memory location.
This is not good when, e.g., we are reading the interrupt register.
Ideally, we would just raise splhigh() in ncr53c9x_readregs(), but
that's m.i. code, and it may be expensive on other architectures.
