    [SPARC64]: Fix central/FHC bus handling on Ex000 systems. · 4130a4b2
    David S. Miller authored
    1) probe_other_fhcs() wants to see only non-central FHC
       busses, so skip FHCs that don't sit off the root
    
    2) Like SBUS, FHC can lack the appropriate address and
       size cell count properties, so add an of_busses[]
       entry and handlers for that.
    
    3) Central FHC irq translator probing was buggy.  We
       were trying to use dp->child in irq_trans_init but
       that linkage is not setup at this point.
    
       So instead, pass in the parent of "dp" and look for
       the child "fhc" with parent "central".
    
    Thanks to the tireless assistence of Ben Collins in tracking
    down these problems and testing out these fixes.
