That feature is enabled on most/all Tegra boards with PCI support. 
Hopefully nobody will miss it; I guess I haven't used it so I don't 
object to this change.

However, wouldn't it be better to remove CONFIG_CMD_PCI_ENUM from the 
config header rather than leaving the command enabled yet 
non-functional? Or are you planning on implementing this path in the 
near future?
