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().
