[PATCH] dpaa2-eth: debugfs: use div64_u64 for division

[Arnd Bergmann]

A plain 64-bit division breaks building on 32-bit architectures:

ERROR: modpost: "__aeabi_uldivmod" [drivers/net/ethernet/freescale/dpaa2/fsl-dpaa2-eth.ko] undefined!

As this function is not performance critical, just use the external
helper instead.
