sky2: implement 64 bit stats
This implements 64 bit statistics support and fixes races when reading
counter values. The PHY counters can only be accessed 16 bits at a time,
so they are subject to carry races.
NB:
* TX/RX counters are maintained in software because the the hardware packet count
is only a 32 bit value.
* Error counters are really only 32 bit.
* Old 32 bit counter fields in dev->stats still used for some
software counters
