I believe the different timeouts in each driver are just coincidence
and partly based on who reviewed which driver.

I'm pretty sure it doesn't really matter at all, and we can just use
the same loop for every one.

I was also hoping that a little more than just the loop could be
unified between the various establish_link() functions. I have a
feeling that each one just implements a subset of what is actually
required, so they are buggy in different ways because nobody
has the datasheet.
