Move initialization of MMCONF BAR to cache_as_ram setup phase, in order
to make sure MMCONF is set up before use. Otherwise, PCI config
accesses run before init_cpus() will be lost if MMCONF is enabled
(unless explicitly done as port-based accesses).
This obsoletes removal of RES_PCI_IO, PCI_ADDR(0, 1, 0, 0x78) in
mcp55_early_setup, so reinsert.
