[ Upstream commit d0d62baa7f505bd4c59cd169692ff07ec49dde37 ]

Printing kernel pointers is discouraged because they might leak kernel
memory layout. This fixes smatch warning:

drivers/net/ethernet/xilinx/xilinx_emaclite.c:1191 xemaclite_of_probe() warn:
argument 4 to %08lX specifier is cast from pointer
