phy_cdc: Allow unlimited clock ratios
...
Actually, assuming that each clock domain is fast enough for 10 MBit/s,
there is no problem running crazy ratios.

phy_cdc: Fix synchronization behavior
...
For low ratios of the two clock domains, the slow clock domain would
receive incorrect data as the fast (PHY) clock domain's data output
would have already updated with the first bit of the next byte by
the time the slow (system) clock domain read it.
This fix registers the data in the source clock domain as opposed
to the destination clock domain. This is allowed because the valid
strobe is synchronized in a way to guarantee that data has been
valid for a while when it becomes asserted.
Additionally, `phy_out.rx_data` and `phy_out.rx_data_valid` are no
longer registered in the destination (system) clock domain as this
now introduces unnecessary latency. Also, this was broken the way
it was anyway as `rx_active` and `rx_error` would've also had to be
registered to keep all timings in sync.
