John Baldwin ae09eb7337 Add locking to adv(4) driver and mark it MPSAFE. 
- Disable the support for the second channel on twin-channel EISA cards as
  the current incarnation can't possibly work correctly (it hasn't worked
  since switching to new-bus where new-bus allocates the softc).  If anyone
  bothers to test this again it can be fixed properly and brought back.
- Use device_printf() and device_get_nameunit() instead of adv_name().
- Remove use of explicit bus space handles and tags.
- Use PCI bus accessors and helper routines rather than accessing
  config registers directly.
- Handle failures from adv_attach().

Tested by:	no one (hope it works)
