vendorcode/intel/fsp/fsp2_0/cpx_sp: Set correct stack number for IOU3
PSTACK2 (IOU3) should be stack number 4, mainboard uses stack number as
the index to access the bus number array read by get_stack_busnos().
Without the fix it would get the wrong bus number (0xb1).
Tested=On OCP Delta Lake, dmidecode -t 9 to verify slots bus number on
IOU3 are correct (0xb2).
