net: atlantic: per-TC queue statistics
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
