Before commit 2953f850c3b80bdca004967c83733365d8aa0aa2 ("[SCSI] ufs:
use devres functions for ufshcd"), UFSHCI register was ioremapped by
each glue-driver (ufshcd-pltfrm and ufshcd-pci) during probing and it
was iounmapped by core-driver during removing driver. The commit
converted ufshcd-pltfrm to use devres functions, but it didn't convert
ufshcd-pci.
Therefore, the change causes ufshcd-pci driver not to iounmap UFSHCI
register region during removing driver. This fixes it by converting
ufshcd-pci to use devres functions.
