northbridge/intel/i945/raminit.c: Remove set but unused variable `reg16`

Removing `-Wno-unused-but-set-variable` from `CFLAGS` results in the
    following error.

CC         northbridge/intel/i945/raminit.romstage.o
    	src/northbridge/intel/i945/raminit.c: In function 'sdram_detect_cas_latency_and_ram_speed':
    	src/northbridge/intel/i945/raminit.c:497:6: error: variable 'lowest_common_cas' set but not used [-Werror=unused-but-set-variable]
    	src/northbridge/intel/i945/raminit.c: In function 'sdram_program_pll_settings':
    	src/northbridge/intel/i945/raminit.c:1955:15: error: variable 'reg16' set but not used [-Werror=unused-but-set-variable]
    	cc1: all warnings being treated as errors

The variable is declared as `volatile`, but as it is not read anywhere
    it can be removed.
