sb/amd/amd8111/acpi.c: Remove set but unused variable `dword` 

Removing `-Wno-unused-but-set-variable` from `CFLAGS` results in the error
below, when building for example the HP DL145 GL1.

	    CC         southbridge/amd/amd8111/acpi.ramstage.o
	src/southbridge/amd/amd8111/acpi.c: In function 'acpi_init':
	src/southbridge/amd/amd8111/acpi.c💯11: error: variable 'dword' set but not used [-Werror=unused-but-set-variable]

Removing the variable `dword` fixes this error.

The read is left in the code, as I do not know if it has an effect or
not.
