PCI: push deprecated pci_find_device() function to last user
The ISDN4Linux HiSax driver family contains the last remaining users
of the deprecated pci_find_device() function. This patch creates a
private copy of that function in HiSax, and removes the now unused
global function together with its controlling configuration option,
CONFIG_PCI_LEGACY.
