New features:

- Moved BCM5706S/5708S SerDes support to brgphy (since they are not technically
  TBI interfaces)
- Added 2.5G support for BCM5708S

Comments:
Since this driver is shared with bge I tested several available controllers
supported by bge and all worked as expected, however the list was not
exhaustive.  Need wider testing.

MFC after:	4 weeks
