net: dsa: Add support for 64-bit statistics
DSA slave network devices maintain a pair of bytes and packets counters
for each directions, but these are not 64-bit capable. Re-use
pcpu_sw_netstats which contains exactly what we need for that purpose
and update the code path to report 64-bit capable statistics.
