soc/intel/tigerlake: Disable CPU PCIe in FSP

In TGL SoC we have PCH and CPU side PCIe support. This patch
skips CPU side PCIe enablemen in FSP if device is disabled in
devicetree. Disabling the initialization of CPU PCIe saves ~30ms
in FspSiliconInit!

BUG=b:158573805
BRANCH=None
TEST=Build and boot volteer and TGL RVP. Using cbmem tool measure
the
boot time. FspSilicontInit time is reduced by ~30ms with
this patch.
