Marius Strobl 04016bcf93 Flesh out support for SAS1078 and SAS1078DE (which are said to actually 
be the same chip):
- The I/O port resource may not be available with these. However, given
  that we actually only need this resource for some controllers that
  require their firmware to be up- and downloaded (which excludes the
  SAS1078{,DE}) just handle failure to allocate this resource gracefully
  when possible. While at it, generally put non-fatal resource allocation
  failures under bootverbose.
- SAS1078{,DE} use a different hard reset protocol.
- Add workarounds for the 36GB physical address limitation of scatter/
  gather elements of these controllers.
