mb/asrock/b75pro3-m: Fix S3 resume and hardware monitoring

On the ASRock B75 Pro3-M, resuming from S3 has always been broken;
see commit 928c6c6336f2 (mainboard/asrock: add ASRock B75 Pro3-M).
This was because 3VSBSW# was not enabled during S3, causing the
board to reboot instead of resume. This change enables 3VSBSW#
during S3, which leads to S3 resume working normally.

Another issue with this board was that hardware monitoring was not
working. The nct6775 Linux kernel module could not be loaded, due to
the device having a base I/O port of 0. This change also enables the
Super I/O properly, so that sensors-detect can find the sensor and
the kernel module can be used.
