RDMA/nes: Add wide_ppm_offset parm for switch compatibility
We have observed unstable link with a new BNT switch.
Add wide_ppm_offset parameter to allow the user to control the clock
ppm offset on the CX4 interface for better compatibility. Default is
100ppm, setting it to 1 will increase it to 300ppm. Change default
SerDes1 reference clock to external source.
