PCI: xilinx: Fix harmless format string warning

Browse source

The xilinx PCIe driver prints a register value whose type is propagated to
the type returned by the GENMASK() macro.  Unfortunately, that type has
recently changed as the result of a bug fix, so now we get a warning about
the type:

  drivers/pci/host/pcie-xilinx.c: In function 'xilinx_pcie_clear_err_interrupts':
  drivers/pci/host/pcie-xilinx.c:154:3: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long unsigned int' [-Wformat=]

Change the code so we always print the number as an 'unsigned long' type to
avoid the warning.  The original code was fine on 32-bit architectures but
not on 64-bit.  Now it works as expected on both.
