ALSA: emu10k1: use more existing defines instead of open-coded numbers 

Using the *_MASK defines for "maximal value" is debatable. I got the
idea from FreeBSD, and it sorta makes sense to me.

Some hunks look a bit incomplete, because code that is going to be
subsequently removed is not touched here.
