AMD Parmer: remove unused macros and turn off unused pcie port

Browse Source 
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].
