PCI: Pass bridge window resource to pbus_size_mem()

PCI: Pass bridge window resource to pbus_size_mem()

pbus_size_mem() inputs type and calculates bridge window resource within.
Its caller (__pci_bus_size_bridges()) also has to look up the prefetchable
window to determine if it exists or not to decide whether to call
pbus_size_mem() twice or once.

Change the interface such that the caller is responsible in providing the
bridge window resource. Passing the resource directly avoids another lookup
for the prefetchable window inside pbus_size_mem().
