The asm/pci.h used for many newer architectures share similar definitions.
Move the common parts to asm-generic/pci.h to allow for sharing code.

This looks to be something that was accidentally left out on the csky port.
Define ARCH_GENERIC_PCI_MMAP_RESOURCE to keep it inline with other ports.
Adding ARCH_GENERIC_PCI_MMAP_RESOURCE enables the definition of modern
pci_mmap_resource_range() functions which is generally what new ports
should be using.

The isa_dma_bridge_buggy symbol is only used for x86_32, and only x86_32
platforms or quirks ever set it.
Add a new linux/isa-dma.h header that #defines isa_dma_bridge_buggy to 0
except on x86_32, where we keep it as a variable, and remove all the arch-
specific definitions.

pci_get_legacy_ide_irq() is only used on platforms that support PNP, so
many architectures define it but never use it. Replace uses of it with
ATA_PRIMARY_IRQ() and ATA_SECONDARY_IRQ(), which provide the same
functionality.
Since pci_get_legacy_ide_irq() is no longer used, remove all the
architecture-specific definitions of it as well as asm-generic/pci.h, which
only provides pci_get_legacy_ide_irq()

Add the pci related code for csky arch to support basic pci virtual
function, such as qemu virt-pci-9pfs.
