baytrail: allow downstream use of SSE instructions

If a payload is compiled to use SSE instructions it will
    fault with an undefined opcode because SSE instructions weren't
    enabled. Therefore enable SSE instructions at runtime.

BUG=chrome-os-partner:22991
    BRANCH=None
    TEST=Built and booted with SSE enabled payload. No exceptions seen.
