serwb: fix rx_delay_inc on ultrascale, this was the issue serwb issue...
...
rx_delay_inc and rx_delay_ce were set for only one cycle, on ultrascale, these signals are translated to serwb_serdes_5x clock domain and we now set rx_delay_inc always to 1 (MultiReg), rx_delay_ce for one cycle (PulseSynchronizer)

gateware/serwb: for the initial version set delay in the center of the valid sampling window and don't use phase detectors
...
we'll use phase detectors later when it will be working reliably for both artix7 and kintex ultrascale
