AMD Parmer: remove unused macros and turn off unused pcie port
1) The macros GNB_GPP_PORTx_PORT_PRESENT, GNB_GPP_PORTx_SPEED_MODE, GNB_GPP_PORTx_LINK_ASPM and GNB_GPP_PORTx_CHANNEL_TYPE are not used. This is based on >AMD Thatcher: remove unused macros in PlatformGnbPcieComplex.h< [1]. 2) Disable unused PCIE port in devicetree.cb. PCIE port 3 is not used in Parmer. This is based on item 3 of >AMD Thatcher: Fix PCIE link issues< [2].
