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.

Move the common parts to asm-generic/pci.h to allow for sharing code. Two things to note are: - isa_dma_bridge_buggy, traditionally this is defined in asm/dma.h but these architectures avoid creating that file and add the definition to asm/pci.h. - ARCH_GENERIC_PCI_MMAP_RESOURCE, csky does not define this so we undefine it after including asm-generic/pci.h. Why doesn't csky define it? - pci_get_legacy_ide_irq, This function is only used on architectures that support PNP. It is only maintained for arm64, in other architectures it is removed.

We discussed limiting it only to x86 though as its a general quick triggered by pci ids I think it will be more tricky than we thought so I will leave as is. It might be nice to move it out of asm/dma.h and into asm/pci.h though.
