baytrail: Basic DPTF framework

Browse Source 
This is not complete yet but it compiles and doesn't cause
any issues by itself.  It is tied into the EC pretty closely
so that is part of the same commit.

Once we have more of the EC support done it will need some
more work to make use of those new interfaces properly.

BUG=chrome-os-partner:17279
BRANCH=none
TEST=build and boot on rambi, dump DSDT and look over \_SB.DPTF
