Enable PCIe slot bifurcation using HX keyword
-Update the PCIe config code to check the contents
of the HX keyword attribute when determining the
lane configuration.
The HX keyword was defined to describe the lane
configuration for a specific PCIe slot.
It is generally stored in the VPD data of a PCIe card
where it is read by the FSP. If the HX keyword
data is populated, the FSP will then update the
PEC_PCIE_HX_KEYWORD_DATA attribute for the
PCIe slot the card is installed in. Once hostboot
reads the HX keyword it will determine the correct
lane configuration and adjust the IOP configuration
attributes for the hardware procedure, p9_pcie_scominit,
to consume.
