ALSA: mixart: Proper endian notations
The miXart driver deals with big-endian values as raw data, while it
declares most of variables as u32. This leads to sparse warnings like
sound/pci/mixart/mixart.c:1203:23: warning: cast to restricted __be32
Fix them by properly defining the structs and add the explicit cast to
macros.
