ALSA: trident: Proper endian notations

Browse Source 
The TLB entries in Trident driver are represented in little-endian,
hence they should be declared as __le32.

This patch fixes the sparse warnings like:
  sound/pci/trident/trident_memory.c:226:17: warning: incorrect type in assignment (different base types)
