wr_gtx_phy_virtex6_lp: increase link down detect threshold so the LPDC PHY does not fail on jumbo frames

Forgot to do that when porting the MDIO stuff to Cheby. Sorry Tristan :/

- we now use Cheby for the MDIO register layout (small changes in the naming)
- dropped LPC_CTRL/LPC_STAT registers in favour of a full WB master interface to the PHY.

It occurred (using Vivado 2021.2) that, when disconnecting the fiber from a timeTransmitter
to a WR node timeReceiver, the link was not be up when re-establishing the connection.
In a disconnect situation rx_cdr_lock starts to toggle (~2x '1', 2x '0' @ 16ns) which was
undetected due to rx_cdr_lock_filtered.
