Marius Strobl 917825acb9 - Don't set CAS_PCS_DATAPATH to anything except CAS_PCS_DATAPATH_SERDES 
on Cassini using the external PCS SERDES otherwise unaligned access
  traps and other strange effects happen with some machines. Don't touch
  the MIF which is unused in that case either. These changes require the
  PHY type to use to be determined via the OFW device tree or from the
  VPD in machines without the former.
- Disable the SERDES pins of Saturn when not used in order to save power
  and ensure they are enabled otherwise.
- In cas_attach() use the correct register offset for CAS_PCS_CONF_EN.
- Add some bus space barriers missing in the PCS code path.

These changes make the Sun GigaSwift Ethernet 1.0 MMF cards as well as
the on-board interfaces found in Sun Fire B100s Blade Server work.
