John Baldwin 313f8941e1 Add locking to the core iicbus(4) drivers: 
- Add an sx lock to the iic(4) driver to serialize open(), close(), read(),
  and write and to protect sc_addr and sc_count in the softc.
- Use cdev->si_drv1 instead of using the minor number of the cdev to
  lookup the softc via newbus in iic(4).
- Store the device_t in the softc to avoid a similar detour via minor
  numbers in iic(4).
- Only add at most one instance of iic(4) and iicsmb(4) to each iicbus(4)
  instance, and do it in the child driver.
- Add a mutex to the iicbus(4) softc to synchronize the request/release bus
  stuff.
- Use __BUS_ACCESSOR() for IICBUS_ACCESSOR() instead of rolling our own.
- Add a mutex to the iicsmb(4) softc to protect softc state updated in the
  interrupt handler.
- Remove Giant from all the smbus methods in iicsmb(4) now that all the
  iicbus(4) backend is locked.
