southbridge/intel/i82801ix/lpc.c: Remove unused variable `dummy`

Removing `-Wno-unused-but-set-variable` from `CFLAGS` the build for
    QEMU Q35 and Roda RK9, both using the Intel 82801Ix southbridge, fail
    with the following error.

src/southbridge/intel/i82801ix/lpc.c: In function 'i82801ix_enable_apic':
    	src/southbridge/intel/i82801ix/lpc.c:45:5: error: variable 'dummy' set but not used [-Werror=unused-but-set-variable]
    	cc1: all warnings being treated as errors

Removing `dummy` should be safe as GCC probably optimizes it away before
    anyway. That no dummy variable is used for an RCBA [1] access in Intel
    Lynx Point supports that this can be dropped safely.
