Update Aic7xxx driver to version 6.2.29

 o Add bus attachment specific hooks for chip-init, suspend and
   resume.  This is a precursor to better suspend and resume support.
 o Fix a bug that could cause unnecessary renegotiations after selection
   timeouts.
 o Fix a hang that occurred if the mid-layer attempted to probe devices
   at the controller's own ID.
 o Add some delays to the termination detection logic for 785X chips.
   This might resolve some termination problems on very early controllers.
