ricoh_mmc: Handle newer models of Ricoh controllers

Browse source

The latest generation of laptops are shipping with a newer
model of Ricoh chip where the firewire controller is the
primary PCI function but a cardbus controller is also present.

The existing code assumes that if a cardbus controller is,
present, then it must be the one to manipulate - but the real
rule is that you manipulate PCI function 0. This patch adds an
additional constraint that the target must be function 0.
