mmc: sdhci-pci: add platform data
Add a means of getting platform data for the SDHCI PCI devices. The data is stored against the slot not the device in order to support multi-slot devices. The data allows platform-specific setup (such as getting GPIO numbers from firmware or setting up wl12xx for SDIO) to be done in platform support files instead of the sdhci-pci driver.
