This patch introduces {PCIX,PCIE,AGP...}_SUPPORT config variables.

Browse source 
Kconfig:
       Add *_SUPPORT variables.
       Add select statements for the hardware that needs them.

device/Makefile:
       Test *_SUPPORT variables instead of chip names.

device/Kconfig:
       Add *_PLUGIN_SUPPORT variables.

device/pci_device.c:
       Conditionally include headers if *_PLUGIN_SUPPORT.
       Update default drivers to depend on CONFIG_*_PLUGIN_SUPPORT.
