phy: add bitslip module (we need to implement it in logic for Kintex Ultrascale since not provided by ISERDESE3)

phy: add initial Kintex Ultrascale PHY (incomplete)
...
Input deserializer still missing, need to implement bitslip in logic and use new fifo interface.
Others primitives should be fine.

frontend/bist: remove LiteDRAMBISTCheckerScope.
...
Checker should not be used to investigate errors but only to verify that is already validated still works. (ie we don't want to be able to understand what is going on, just to know if it's working or not). To understand what is going on we will look at signals with LiteScope and eventually trigger on err_count from checker.
