This patch adds support for the Ricoh RL5c476 chip: with this
the mmc adapter that needs this disabler (R5C843) can also be
handled correctly when it sits on a RL5c476.

As pci config space is reinitialised on a suspend/resume cycle, the
disabler needs to work its magic at resume time. For symmetry this
change also explicitly enables the controller at suspend time but
it's not strictly necessary.

Thanks to Matt Domsch and Rezwanul Kabir at Dell, we know how to disable the
MMC controller on the multi-function Ricoh R5C832. The MMC controller needs
to be disabled or it will steal MMC cards from the SD controller where they
would otherwise be supported by the Linux SDHCI driver.
