southbridge/intel/i82801gx: Make compilation possible with CONFIG_SMM_TSEG

Without that fix, and with CONFIG_SMM_TSEG, we have:
  src/southbridge/intel/i82801gx/smihandler.c: In function 'southbridge_smi_sleep':
  src/southbridge/intel/i82801gx/smihandler.c:340:3: error: implicit declaration of function 'smi_release_lock' [-Werror=implicit-function-declaration]
  cc1: all warnings being treated as errors
  make: *** [build/southbridge/intel/i82801gx/smihandler.smm.o] Error 1

The fix is modelled after src/cpu/x86/smm/smihandler.c which
  ifdefs smi_release_lock().
