This patch adds support for the VIA VT8237S south bridge. The VT8237R programming remains unchanged (tested
on mine desktop) except of reverting the small change introduced by Bari (gpio/inta setup reg 0x5b). This should go for some board specific file. The change would broke at least mine board. But seems to be needed for jakllsch.
