how about the simpler fix below, as a first-level approach? We can then
remove the _p in/out sequences after this.
I believe this will suffer from the issue that was raised: this will use
udelay() long before loop calibration (and no, we can't just "be
conservative" since there is no "conservative" value we can use.)

until 6GHz cpus come out.
How long will that take to boot on a 386?
