ricoh_mmc: port from driver to pci quirk

This patch solves nasty problem original driver has.

Original goal of the ricoh_mmc was to disable this device because then,
mmc cards can be read using standard SDHCI controller, thus avoiding
writing of yet another driver.

However, the act of disablement, makes other pci functions that belong to
this controller (xD and memstick) shift up one level, thus pci core has
now wrong idea about these devices.

To fix this issue, this patch moves the driver into the pci quirk section,
thus it is executes before the pci is enumerated, and therefore solving
that issue, also same sequence of commands is performed on resume for same
reasons.

Also regardless of the above, this way is cleaner.  You still need to set
CONFIG_MMC_RICOH_MMC to enable this quirk
