Moved splhigh()/spl0() calls from isa_configure() to configure() so that

there is a natural place to initialize `safepri' in a future commit.
Spinoffs:
- spl0() gets called in the unlikely event that isa is not configured.
- configure() has better control over enabling interrupts.
- it is now less unclear that interrupts aren't actually enabled early.
  Rev.1.48 of autoconf.c seems to have done the opposite of what was
  intended - moving the isa_configure() call delayed the spl0() side
  effect.
Added some comments about the bogons.  Removed the splhigh() call since
it is a no-op.
