sb/intel/bd8x62x,i82801gx: Fix PCI bridge subsystem IDs
Implementation of ich_pci_dev_enable_resources() used to have a custom implementation to program PCI subsystem IDs for the (legacy) PCI bus bridge. With the local implementation removed, we no longer need the custom .enable_resources callback.
