[mubios] Fix legacy interrupt routing and enable PIIX IDE channels
Keep IOAPIC inputs masked and deliver legacy PIC interrupts through LVT0
only, avoiding extra ExtINT routes that leave PIC and APIC interrupts
in service.
Enumerate the root PCI bus for the PIIX3 IDE controller during POST.
Enable I/O decoding and both IDE channels while preserving their timing
configuration so Linux ata_piix probes the disks.
