Sean Anderson 02069bceee pcs: Add false_carrier signal
This adds an explicit false carrier signal. Trying to determine this
condition the MDIO signals is tricky because BAD_SSD can last over
several cycles of CE. To make things easier, add a signal which is high
only once per event.

Sean Anderson 7d35e07401 mdio_regs: Add support for counters
This adds support for counters for interesting conditions (disconnects,
PMD phase wraparounds, errors, etc). All the counters are 15 bits
instead of 16, because 16-bit counters have an fmax of 110MHz or so. All
the counters live behind a condition because they ~double the number of
resources used.
