The generic pci.h header now only provides a definition of
pci_get_legacy_ide_irq which is used by architectures that support PNP.
Of the architectures that use asm-generic/pci.h this is only x86.
This patch removes the old pci.h in order to make room for a new
pci.h to be used by arm64, riscv, openrisc, etc.
The existing code in pci.h is moved out to x86. On other architectures
we clean up any outstanding references.

Since v2:
- Remove pci_get_legacy_ide_irq in m68k
Since v1:
- Remove pci_get_legacy_ide_irq for most architectures as its not needed.
