soc/intel/apollolake: Sync FSP PCIE NPK device as per devicetree 

This patch makes our devicetree in sync with the FSP configuration.
Without this we see in boot logs "PCI: 00:00.2 not found,
disabling it". The reason being in FSP NPK device is disabled by
default. We can enable it by enabling the UPD parameter TraceHubEn.
If we enable it in FSP then the logs complain the NPK pcie device
is not seen.

BUG=b:76115112
TEST=Build for Octopus and check that the logs do not report
"PCI: 00:00.2 not found, disabling it".
