0e7e521cf3 Allow a DMA channel of 0. This gets the on-board mss audio device working 
on Digital AlphaStations 200 and 500 machines (and probably others as well).

25afb89b1c * Add struct resource_list* argument to resource_list_alloc and 
resource_list_release. This removes the dependancy on the
  layout of ivars.

* Move set_resource, get_resource and delete_resource from
  isa_if.m to bus_if.m.

* Simplify driver code by providing wrappers to those methods:

     bus_set_resource(dev, type, rid, start, count);
     bus_get_resource(dev, type, rid, startp, countp);
     bus_get_resource_start(dev, type, rid);
     bus_get_resource_count(dev, type, rid);
     bus_delete_resource(dev, type, rid);

* Delete isa_get_rsrc and use bus_get_resource_start instead.

* Fix a stupid typo in isa_alloc_resource reported by Takahashi
  Yoshihiro <nyan@FreeBSD.org>.

* Print a diagnostic message if we can't assign resources to a PnP
  device.

* Change device_print_prettyname() so that it doesn't print
  "(no driver assigned)-1" for anonymous devices.

bea6af4d31 * Change device_add_child_after() to device_add_child_ordered() which is 
easier to use and more flexible.
* Change BUS_ADD_CHILD to take an order argument instead of a place.
* Define a partial ordering for isa devices so that sensitive devices are
  probed before non-sensitive ones.

a3be63b3ce * Factor out the common code between the isa bus drivers for i386 and alpha. 
* Re-work the resource allocation code to use helper functions in subr_bus.c.
* Add simple isa interface for manipulating the resource ranges which can be
  allocated and remove the code from isa_write_ivar() which was previously
  used for this purpose.

6c2e3dde8c * Define a new static method DEVICE_IDENTIFY which is called to add device 
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.
