Documentation - Create laptops sub-directory

There are currently various laptop drivers floating about with no central
place for their documentation, which is currently scattered around the top
level Documentation/ directory.

So, as a first step, lets create a Documentation sub-directory, and update
the relevant index files. The work of then moving the existing laptop
driver related documentation will then be handled later.
