    Remove transparent bridge sizing.
    
    Due to code in pci_read_bridge_bases() [drivers/pci/probe.c] the child
    bus of a transparent bridge already has access to the parent bus
    resources so transparent bridge sizing appears unnecessary.  The bridge
    sizing includes alignment and granularity adjustments that can cause
    significantly more memory to be reserved from the parant bus than
    required by devices on the child bus and allotted by _CRS.
