soc/intel/xeon_sp: Use fixed BDF for IBL

Integrated Boot Logic (IBL) codes doesn't support bootloader
controlled Primary-to-Sideband Bridge (P2SB) hidden and unhidden.
Hence, dynamically read IBL HPET/IOAPIC Bus:Device.Function (BDF)
by bootloader is not supported, because when P2SB is hidden the
register access is denied.
