dpaa2-eth: Use proper division helper in dpaa2_dbg_ch_show 

When building arm32 allmodconfig:

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

frames and cdan are both of type __u64 (unsigned long long) so we need
to use div64_u64 to avoid this issues.
