net: aquantia: add PTP rings infrastructure

Browse source 
Add implementations of PTP rings alloc/free.

PTP desing on this device uses two separate rings on a separate traffic
class for traffic rx/tx.

Third ring (hwts) is not a traffic ring, but is used only to receive timestamps
of the transmitted packets.
