siemens/mc_apl3: Set Full Reset Bit into Reset Control Register
This mainboard provides customer hardware reset button. A feature of this button is that it holds the APL in reset state as long as the reset button is pressed. After releasing the reset button the APL should restart again without the need for a power cycle. When Bit 3 in Reset Control Register (I/O port CF9h) is set to 1 and then the reset button is pressed the PCH will drive SLP_S3 active (low).
