soc/skylake: do not rely on P2SB data to generate DRHD
The P2SB PCI device can be "hidden", which causes all sorts of
nightmares and bugs. Moreover, FSP tends to hide it, so finding
a good solution to this problem is impossible with FSP into the mix.
Since the values for IBDF and HBDF were already hardcoded as FSP
parameters, define them as macros and use these values directly to
generate the DRHD.
