MFC r289726:
Add iicbus_transfer_excl(), a helper routine to do an i2c bus transaction
while holding exclusive ownership of the bus. This is the routine most
slave drivers should use unless they have a need to acquire and hold the
bus across a series of related operations that involves multiple transfers.
