mb/supermicro/x10slm-f: Do SIO setup in bootblock

Lynx Point switched to doing mainboard-specific super I/O setup in the
bootblock with commit d893a2635fdd ("sb/intel/lynxpoint: Enable LPC/SIO
setup in bootblock"). The X10SLM+-F was added while that commit was in
review, and hence did not receive the necessary changes to SIO setup.

This patch has not been tested on hardware.
