ALSA: via82xx: Fix endianness annotations
The internal page tables are in little endian, hence they should be
__le32 type. This fixes the relevant sparse warnings:
sound/pci/via82xx.c:454:60: warning: incorrect type in assignment (different base types)
sound/pci/via82xx.c:454:60: expected unsigned int [usertype]
sound/pci/via82xx.c:454:60: got restricted __le32 [usertype]
....
No functional changes, just sparse warning fixes.
