pci: Add a quirk for the Ricoh 0xe22 SD card reader

Otherwise it fails like this on cards like the Transcend 16GB SDHC card:
mmc0: new SDHC card at address b368
mmcblk0: mmc0:b368 SDC   15.0 GiB
mmcblk0: error -110 sending status command, retrying
mmcblk0: error -84 transferring data, sector 0, nr 8, cmd respons
e 0x900, card status 0xb0

Tested on my Lenovo x200 laptop.

Hi Bjorn-

I want to make sure this doesn't get lost.  It's a patch for pci, not
for mmc, despite the subject.

Ping -- this is an important patch for getting SD cards working on
Thinkpads, please can you pick it up?

I put this in my for-linus branch, which will become part of v3.8.
Thanks for the reminder!
