mmc: sdhci-pci: Let devices define their own private data
Let devices define their own private data to facilitate device-specific
operations. The size of the private structure is specified in the
sdhci_pci_fixes structure, then sdhci_pci_probe_slot() will allocate extra
space for it, and sdhci_pci_priv() can be used to get a reference to it.
