sb/intel/i82801jx: Use common Intel SMM code

Use the common Intel code to set up smm and the smihandler.
This is expected to break S3 resume and other smihandler related
functionality as this code is meant to be used with CONFIG_SMM_TSEG.
The platform (x4x) using this southbridge will adapt
the CONFIG_SMM_TSEG codepath in subsequent patches.
