Google Link: Add remaining code to support native graphics

The Link native graphics commit 49428d84 [1]

Add support for Google's Chromebook Pixel

was missing some of the higher level bits, and hence could not be
    used.  This is not new code -- it has been working since last
    August -- so the effort now is to get it into the tree and structure
    it in a way compatible with upstream coreboot.

1. Add options to src/device/Kconfig to enable native graphics.
    2. Export the MTRR function for setting variable MTRRs.
    3. Clean up some of the comments and white space.

While I realize that the product name is Pixel, the mainboard in the
    coreboot tree is called Link, and that name is what we will use
    in our commits.
