lib/bitmap.c: change prototype of bitmap_copy_le
Make the prototype of bitmap_copy_le the same as bitmap_copy's. All other bitmap_* functions take unsigned long* parameters; there's no reason this should be special. The only current user is the static inline uwb_mas_bm_copy_le, which already does the void* laundering, so the end users can pass their u8 or __le32 buffers without a cast. Furthermore, this allows us to simply let bitmap_copy_le be an alias for bitmap_copy on little-endian; see next patch.
