Angel Pons 436f1c471a mb/siemens/mc_apl*: Enable early PCI bridge before FSP-M 
Apollo Lake seems to start with PCIe root ports unusable/uninitialized
before FspMemoryInit() is called and FSP-M properly initializes these
root ports.

However, we need the root ports accessible before FspMemoryInit() in
certain cases, such as emitting POST codes through a PCIe device.

For the initialization to happen properly, certain register writes
specified in Apollo Lake IAFW BIOS spec, vol. 2 (#559811), chapter
3.3.1 have to be done.

BUG=none
TEST=Boot on siemens/mc_apl2 with NC_FPGA_POST_CODE enabled and check
that the POST codes are emitted before FspMemoryInit().
