ShellPkg/mm: Fix mm to support multiple root bridge platform
In multiple root bridge platforms, different root bridges may
share the same segment but occupy different range of buses,
or may occupy different segments.
The fix is to find the correct root bridge IO instance by
comparing not only the segment but also the bus ranges.
It tries to access the MMIO and IO in the following order:
PciRootBridgeIo, CpuIo and direct IO.
