sdhci: Pass drive parameter to sdhci-pci via qdev property

Browse source 
Commit 19109131 disabled the sdhci-pci support because it used
drive_get_next().  This patch reenables sdhci-pci and changes it to
pass the drive via a qdev property - for example:
 -device sdhci-pci,drive=drive0 -drive id=drive0,if=sd,file=myimage
