Some resets associated with venus require a larger delay for the hardware
on the other end to function properly. These seem to fall into three
categories:

- 150us for 8250 and earlier
- 400us for 8350 and friends
- 1000us for >=8450

Make some housecleaning changes and describe these delays in preparation
to moving this data out of the venus driver.
