sb/i82801gx: Don't rewrite over BCTRL
PCI_MIN_GNT is defined at offset 0x3e in <pci_def.h> which does not apply to this PCI bridge because it is only defined for "Header type 0 (normal devices)" (line 82).
BCTRL registry for D30:F0 is defined at offset 0x3e for i82801gx (see ICH7 Family Datasheet page 355). The write on that register is already done some lines above. So remove wrong register name and the wrong code line.
