[U-Boot] [PATCH 2/3] Reset interrupted i2c slaves (galaxy5200)

You may want to talk to Heiko (on CC) about this deblocking stuff.
Heiko implemented an algorithm which seems to work very good for a lot
of different cpu types.

I think it may be worth to reuse what's available there.  And much more,
the algorithm Heiko has implemented has been thoroughly tested on actual
hardware whereas from your commit-msg it seems that your implementation
is more a theoretical one at the moment.

Cheers
  Detlev
