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.
