s390x/pci: use hashtable to look up zpci via fh

After PCI multibus is supported, more than 32 PCI devices could be
plugged. The current implementation of s390_pci_find_dev_by_fh()
appears low performance if there's a huge number of PCI devices
plugged. Therefore we introduce a hashtable using idx as key to store
zpci device's pointer on account of translating fh to idx very easily.
