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.

   text    data     bss     dec     hex filename

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
