Andres Salomon 603ded16a3 olpc: sdhci: add quirk for the Marvell CaFe's interrupt timeout
The CaFe chip has a hardware bug that ends up with us getting a timeout
value that's too small, causing the following sorts of problems:

[   60.525138] mmcblk0: error -110 transferring data
[   60.531477] end_request: I/O error, dev mmcblk0, sector 1484353
[   60.533371] Buffer I/O error on device mmcblk0p2, logical block 181632
[   60.533371] lost page write due to I/O error on mmcblk0p2

Presumably this is an off-by-one error in the hardware.  Incrementing
the timeout count value that we stuff into the TIMEOUT_CONTROL register
gets us a value that works.  This bug was originally discovered by
Pierre Ossman, I believe.

[thanks to Robert Millan for proving that this was still a problem]
