wl1271: moved scan operations to a separate file

The scanning code is going to get a bit more complex, with proper support for
active/passive scans together with 2.4GHz and 5GHz.  In the future, also a
new type of scan (periodic scan) will be added.  When all this is
implemented, the code is going to be much more complex, so we'd better
separate it into a separate file.

This patch doesn't have any impact on functionality.
