net: atlantic: QoS implementation: multi-TC support

This patch adds multi-TC support.

PTP is automatically disabled when the user enables more than 2 TCs,
otherwise traffic on TC2 won't quite work, because it's reserved for PTP.

net: aquantia: replace AQ_HW_WAIT_FOR with readx_poll_timeout_atomic

David noticed the original define was hiding 'err' variable
reference. Thats confusing and counterintuitive.

Andrew noted the whole macro could be replaced with standard readx_poll
kernel macro. This makes code more readable.

net: ethernet: aquantia: return -ETIME in macro AQ_HW_WAIT_FOR

The macro is returning ETIME which means various checks to see if
the returned err is less than zero never work. I believe a -ETIME
should be returned instead.
