Subject: [PATCH 1/2] platform/x86: Move Lenovo files into lenovo subdir

Move all Lenovo specific files into their own sub-directory as part
of clean-up exercise.
Longer term goal is to break-up thinkpad_acpi to improve maintainability
and perhaps share more functionality with other non thinkpad Lenovo
platforms.

Signed-off-by: Mark Pearson <mpearson-lenovo@...ebb.ca>

Some questions that I didn't want to put in the commit comment:

 - I didn't know if now was a good time to propose this change. I
   realise it could cause headaches for anybody with patches being
   worked on. Please let me know what makes it easiest for maintainers
   and other developers. If there is a particular branch that would be
   better to do this against also let me know.
 - Should I be updating the MAINTAINERS file? I'm still not sure what
   the protocol there is. I'm very happy to help review anything in the
   lenovo directory, but I didn't want to make assumptions.
 - I have tested on multiple platforms but I don't have any ideapads I
   can use.
