mb/siemens/mc_apl2: Enable early POST through NC_FPGA
Enable early POST code output for this mainboard, using
the NC FPGA device on PCIe.
This requires the parent PCI bridge to be initialized early.
BUG=none
TEST=boot on siemens/mc_apl2 and observe whether the POST
codes coming from before FSP-M init are visible
