[PATCH] PCI: xilinx: make of_device_ids const.

[Arvind Yadav]

of_device_ids are not supposed to change at runtime. All functions
working with of_device_ids provided by <linux/of.h> work with const
of_device_ids. So mark the non-const structs as const.

File size before:
   text    data     bss     dec     hex filename
    195     600       0     795     31b drivers/pci/host/pcie-xilinx.o

File size after constify xilinx_pcie_of_match:
   text    data     bss     dec     hex filename
    595     184       0     779     30b drivers/pci/host/pcie-xilinx.o
