[dts] [PATCH 1/4] framework: add new module for load port configuration file

[Marvin Liu <yong.liu@intel.com>]

From: Yong Liu <yong.liu@intel.com>

Config module will load port configuration and parse port parameter.
Port configuration will be used in the process of setting up DUT.
User can assign port mac, numa or tester peer pci address of DUT port.
