Patch for ymfpci in 2.4.4

[Pete Zaitcev]

Hello:

Here are updates from ALSA. The interrupt acknowledge has a
potential bug report for it in RH bugzilla. Power-up fix I include
"just because", Alan bounced it to me from sound-hackers;
Also Jeff Garzik asked for it. I wanted to include it with
full PM support, but perhaps not.
