[netdrvr wan] farsync driver update

1) Provides support for new FarSync cards T1U, T2U, T4U and TE1
2) Provides support for an E1 interface
3) Provides support for a variant of X.21 that allows transmit and
receive clocks
4) Provide a raw socket interface directly to the data from the line.
5) Improves performance with less time in interrupts and more in BH's
