  Modified files:
    sys/sparc64/isa      isa.c 
  Log:
  - When iterating over the register resources of the children don't use
    the iteration variable as the RID when adding the respective resource
    to the child via bus_set_resource(). In case a device has both I/O
    and memory resources this generates gaps in the newbus resources of
    the child, e.g. its first memory resource might end up as RID 1.
    To solve this mimic resource_list_add_next() via resource_list_find()
    and bus_set_resource(); we can't just use resource_list_add_next()
    here as this would circumvent the limit checks in isa_set_resource()
    of the common ISA code.
    This however is more or less a theoretical problem so far as all known
    ISA devices on sparc64 soley use I/O space.
  - Just use bus_generic_rl_release_resource() for isa_release_resource()
    instead of re-implementing the former.
  - Improve some comments to better reflect reality, minor clean-up and
    simplifications, return NULL instead of 0 were appropriate.
