intel/kunimitsu: csme: program sml gpios for csme power gating
For SMT controllers to power gate, all SMT/SMS clock, data and alert signals should be inactive.
The SML0 blocks are not used for any functional purposes and are not configured in the GPIO tables.
SMT hardware will not allow the blocks to be power gated in this scenario. The SML* pins are
now configured as GPIOs - input and deep.
With this change, the SMT blocks are properly power gating.
BRANCH=none
BUG=chrome-os-partner:45618
TEST=build for Kunimitsu, boot on FAB3.
