Lars-Peter Clausen 09ffe42603 ad_lvds_in: Allow to disable IDELAY 
The IDELAY is not always required, but it eats up power when instantiated. Allow to disable it.

Lars-Peter Clausen 45f87b46c2 ad_lvds_in: Use "SAME_EDGE" mode 
Currently the IDDRs are configured in SAME_EDGE_PIPELINED mode, but then
the negative data is delayed by an additional clock cycle. This is the same
behaviour as using the IDDR in SAME_EDGE mode.

Switching to SAME_EDGE mode removes extra pipelining registers while
maintaining the same behaviour.

Istvan Csomortani ff980551e6 ad_serdes: SERDES_FACTOR handover missing 
In modules ad_serdes_in/ad_serdes_out the handover of the parameter
SERDES_FACTOR did not exist, causing unwanted behavioral in case of
factors less than 8.
SERDES_FACTOR must be hand over to DATA_WIDTH parameter of the SERDES
primitive.
