* * Factor out the common code between the isa bus drivers for i386 and alpha.dfr1999-05-221-16/+19

* * Define a new static method DEVICE_IDENTIFY which is called to add devicedfr1999-05-141-0/+131
instances to a parent bus. * Define a new method BUS_ADD_CHILD which can be called from DEVICE_IDENTIFY to add new instances. * Add a generic implementation of DEVICE_PROBE which calls DEVICE_IDENTIFY for each driver attached to the parent's devclass. * Move the hint-based isa probe from the isa driver to a new isahint driver which can be shared between i386 and alpha.
