ad9081_fmca_ebz/vcu118: Adjust QPLL params and diff swing 

This commit fixes the 16.5Gbps lane rate case where the link drops
after few seconds an initial successful link up happens.
A few seconds delayed calibration process can workaround this but with
having the differential drivers swing increased this is no longer
required.
