d7fac9732b Allow iic bridges to support a generalized transfer, rather than
forcing all transfers to do the start read/write stop by hand.  Some
smart bridges prefer this sort of operation, and this allows us to
support their features more easily.  When bridges don't support it, we
fall back to using the old-style opertaions.  Expand the ioctl
interface to expose this function.  Unlike the old-style interface,
this interface is thread safe, even on old bridges.

9c77e81b5d make iicbb_devclass and iicbb_driver globally visible. This will let
drivers that implemnt the i2c bit banging bus interface not have to
recompile iicbb in order to add an attachment for it.

This will mean the bktr and other definitions can go back to their
respective drivers.

bf896bd0e2 Change /dev/smb and /dev/iic interface to allow user programs to interact with
devices dynamically. That means,

        + only one /dev/iic or /dev/smb device for each smb/iic bus to access
        + I2C/SMB device address must be given to any ioctl
        + new devices may be plugged and accessed after boot, which was
          impossible previously (device addresses were hardcoded into
          the kernel)
