John Baldwin 13e3657b7b Add locking to the various iicbus(4) bridge drivers: ... - Just grab Giant in the ixp425_iic(4) driver since this driver uses a shared address/data register window pair to access the actual I2C registers. None of the other ixp425 drivers lock access to these shared address/data registers yet and that would need to be done before this could use any meaningful locking. - Add locking to the interrupt handler and 'iicbus_reset' methods of the at91_twi(4) driver. - Add locking to the pcf(4) driver. Other pcf(4) fixes include: - Don't needlessly zero the softc. - Use bus_foo rather than bus_space_foo and remove bus space tag and handle from softc. - The lpbb(4) driver just grabs Giant for now. This will be refined later when ppbus(4) is locked. - As was done with smbus earlier, move the DRIVER_MODULE() lines to match the bus driver (either iicbus or iicbb) to the bridge driver into the bridge drivers.
