net: atlantic: per-TC queue statistics

Browse source 
This patch adds support for per-TC queue statistics.

By default (single TC), the output is the same as it used to be, e.g.:
     Queue[0] InPackets: 2
     Queue[0] OutPackets: 8
     Queue[0] Restarts: 0
     Queue[0] InJumboPackets: 0
     Queue[0] InLroPackets: 0
     Queue[0] InErrors: 0

If several TCs are enabled, then each queue statistics line is prefixed
with TC number, e.g.:
     TC0 Queue[0] InPackets: 6
     TC0 Queue[0] OutPackets: 11
Queue numbering is end-to-end, so:
     TC1 Queue[4] InPackets: 0
     TC1 Queue[4] OutPackets: 22
