Subject: [PATCH v3 0/2] Updates for asm-generic/pci.h

When reviewing the OpenRISC PCI support patch Arnd suggested that
we avoid copying arm64 and riscv asm/pci.h and moving that to be
the new asm-generic/pci.h.

This patch does that by first moving the old pci.h definition
of pci_get_legacy_ide_irq out to the architectures that use it,
this turns out to only be x86.

Next, we create the new pci.h definition.

Note, for the series, I am working on these fixups as part of adding PCI to
OpenRISC.  If the series is accepted I would like to merge via the OpenRISC tree
with the OpenRISC PCI support patches to avoid having to coordinate upstream
merges.

Since v2:
 - Remove pci_get_legacy_ide_irq from m68k.
Since v1:
 - Remove definition of pci_get_legacy_ide_irq on architectures
   not using CONFIG_PNP, which eliminated most.
 - Add ifdef around PCIBIOS_MIN_MEM for consistency.


Stafford Horne (2):
  asm-generic: Remove pci.h copying remaining code to x86
  asm-generic: Add new pci.h and use it
