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.
