ALSA: ice1724: Enable MIDI on TerraTec PHASE 22 and PHASE 28

Even though MIDI was fixed on ice1724 chips a while ago, it wasn't yet
enabled for some cards as it didn't get enough testing. This was tested
with MIDI keyboard on PHASE 22 and with looping back output to input and
it works stable, so it's safe to enable it.

Besides this, there are some more minor fixes, not exactly user visible:
* added info about PHASE 28 (collected, as I don't have a card)
* added info about TS22PCI and new revisions of PHASE 22
* disable 192k on PHASE 22 as AK4524 I2S doesn't support it
* enable SPDIF reciever on PHASE 22
