config, x86: swap bus_id of ISA/PCI in X86 IntelMPTable This patch assign bus_id=0 to PCI bus and bus_id=1 to ISA bus for X86 platform. Because PCI device get config space address using Pc::calcPciConfigAddr() which requires "assert(bus==0)". This fixes PCI interrupt routing and discovery on Linux.
