When the ad1848/cs2431 is first being initialized, auto-calibration may not be set causing a timeout waiting for it in snd_ad1848/cs4231_mce_down(). This has no dire consequences other than an alarming printk, but since what we need to wait for is for the calibration to _finish_, let's just check for that instead. The early chips need a slight delay (as commented -- 5 sample periods) to be sure that _if_ calibration is going to happen, it has started when we check While the CS4231A datasheet implies it'll happen immediately on downing MCE, some testing is showing that there's a window there as well, so just do the delay everywhere.
