The internal page tables are little endian, hence they should be
__le32 type. This fixes the relevant sparse warning:
sound/pci/emu10k1/emu10k1_main.c:2013:51: warning: incorrect type in assignment (different base types)
sound/pci/emu10k1/emu10k1_main.c:2013:51: expected unsigned int [usertype]
sound/pci/emu10k1/emu10k1_main.c:2013:51: got restricted __le32 [usertype]
No functional changes, just sparse warning fixes.
