sb/intel/lynxpoint: Provide a function for mainboard super I/O config
The super I/O setup needs to be done after the LPC is enabled. For
Lynx Point, configuring the super I/O in `mainboard_romstage_entry()`
is too early to get a serial console output. To remedy this, add a
function `mainboard_config_superio()` that will be called at the
appropriate time, and can be overridden by mainboard code.
