Make sure that the retimer is accessible before registering to avoid
having later consumer calls fail to configure it, something which, for
example, can lead to a hotplugged display not being recognised:

unfortunately, this one goes south on the HP Omnibook X14, and also on
the Elitebook G1Q. After excluding a lot of other causes, like inverted
resets and wrong i2c channels, I did a bisect and landed at this commit.

Looking at it, I speculatively increased the firmware initialization
delay to 200ms. To no effect. Reverting this patch "resolves" the issue.

with best regards

Jens
