mmc: use pci_dev->revision

The SDHCI driver uses PCI_CLASS_REVISION instead of PCI_REVISION_ID, so
it was not converted by commit 44c10138fd4bbc4b6d6bff0873c24902f2a9da65
(PCI: Change all drivers to use pci_device->revision). The newer VIA
driver has similar code too. This patch converts both drivers to use
the 'revision' field of 'struct pci_dev'.
