Add machine driver for Broadwell + rt5650.

v2 (Curtis):
* Addressed Pierre's comments
  * Added SOF dependencies
  * Added platform override
  * Fixed Kconfig
* Moved to devm register

Not sure what the recommendation is when an address is no longer valid?

Please delete unneeded context from mails when replying.  Doing this
makes it much easier to find your reply in the message, helping ensure
it won't be missed by people scrolling through the irrelevant quoted
material.
