This will allow us to consult more info before deciding whether to flip
or do a full mode set.

v2:
  - don't use uninitialized or incorrect pipe masks in set_config
    failure path (Ander)
v3:
  - fixup for pipe_config changes in compute_config (Jesse)

Did you mean to convert this to intel_set_mode_pipes()? Since you 
changed intel_set_mode() to do exactly the same thing as above, the 
whole hunk seems unnecessary unless you really care about logging that 
it was the prepare step that failed.

Ah yeah forgot to drop the above bits.  I think it's easier to just
call set_mode here rather than duplicating more compute_config bits.
I'll do that.

Thanks,
