  Log:
  - Split the bus probe function into a bus probe and a bus attach function
    with the attaching of the children done in the bus attach function like
    it's supposed to be.
  - In the bus probe nomatch function print the resources of the children
    like it's done in the other sparc64 specific bus drivers.
  - For the clock frequency IVAR use the per-child values and fall back to
    the bus default in case a child doesn't have the respective property
    instead of always using the bus default so a child driver doesn't need
    to obtain the per-child value itself (see also the commit message of
    sys/dev/esp/esp_sbus.c rev. 1.7).
  - Add support for pass-through allocations. The comment preceding
    sbus_alloc_resource() wasn't quite correct, we need to support pass-
    through allocations for the 'espdma' and 'ledma' (pseudo-)busses which
    hang off of the SBus in Ultra 1 machines. There can also be actual
    bridges like the SBus-to-PCMCIA bridge on the SBus and the XBox (SBus
    extension box) probably also involves one.
