Sean Anderson db41a68f1a mdio_regs: Delay counter signals by one clock 
The counters in this module end up on the critical path a lot.  The
counters themselves take 3-4 ns to compute, but routing the increment
signal to the counter eats up a lot of slack. Register the increment signal
for a clock to let it cross the FPGA without affecting the counter timing.
