AMD Thatcher: Fix PCIE link issues

1). Thatcher PCIE x8 slot is reverse order.
    Although the PCIE slot is x16, it actually uses 8 lanes(15:8).
    Because the PCIE slot is configured by PortList[0], fix this item can enable the slot.
    A x1 PCIE network adapter works well in this slot.

2). Fix DdiList to detect DP monitor or HDMI monitor.
    GPIO50 can be used to detect DP0/HDMI0 monitor.
    If GPIO50 is 1, it is DP monitor. If GPIO50 is 0, it is HDMI monitor.
    GPIO51 can be used to detect DP1/HDMI1 in the same way.

3). Disable unused PCIE port and clean up code in PlatformGnbPcie.c and devicetree.cb.
    PCIE port 3 and 7 are not used in Thatcher.
