We've had some non-arch-specific stuff (pci_has_flag() and associated

  drivers/pci/host/pcie-designware.c:562:20: error: 'PCI_PROBE_ONLY' undeclared (first use in this function)
  drivers/pci/host/pcie-designware.c:562:7: error: implicit declaration of function 'pci_has_flag' [-Werror=implicit-function-declaration]

because arches don't consistently supply asm/pci-bridge.h, and several
drivers include it when they shouldn't.

This series moves the generic stuff to linux/pci.h, so it's the same for
everybody, and removes the now-empty asm-generic/pci-bridge.h.

There still a few arches that provide asm/pci-bridge.h (microblaze,
powerpc, and xtensa), but now they contain truly arch-dependent things like
struct pci_controller definitions, and they're only included by
arch-specific files.
