John Baldwin 85064e683c Various updates to most of the smbus(4) drivers:
- Use printf() and device_printf() instead of log() in ichsmb(4).
- Create the mutex sooner during ichsmb(4) attach.
- Attach the interrupt handler later during ichsmb(4) attach to avoid
  races.
- Don't try to set PCIM_CMD_PORTEN in ichsmb(4) attach as the PCI bus
  driver does this already.
- Add locking to alpm(4), amdpm(4), amdsmb(4), intsmb(4), nfsmb(4), and
  viapm(4).
- Axe ALPM_SMBIO_BASE_ADDR, it's not really safe to write arbitrary values
  into BARs, and the PCI bus layer will allocate resources now if needed.
- Merge intpm(4) and intsmb(4) into just intsmb(4).  Previously, intpm(4)
  attached to the PCI device and created an intsmb(4) child.  Now,
  intsmb(4) just attaches to PCI directly.
- Change several intsmb functions to take a softc instead of a device_t
  to make things simpler.
