soc/amd/*/northbridge,root_complex: simplify mmconf_resource index 

In the northbridge's and root complex' read_resources function, the
mmconf resource used the number of the MMIO_CONF_BASE MSR as index which
might be misleading. Instead use idx++ as a unique index for this
resource.

TEST=Resource allocator doesn't complain and no related warnings or
errors in dmesg. The update_constraints console output changes like
expected:

Before: PCI: 00:00.0 c0010058 base f8000000 limit fbffffff mem (fixed)
After: PCI: 00:00.0 06 base f8000000 limit fbffffff mem (fixed)
