[dts] [PATCH v3 2/4] framework config: support suite&case level configuration

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

Suite level configuration will be shared with all cases belonged to the
suite. Case level configuration will be used just in the case. Case
level configuration will overlap those suite level configurations.

Few types of data are supported in suite&case level configuration.
They are "value_int", "value_hex", "list_int", "list_str" and default
string type. For more details, please reference to
conf/suite_sample.cfg.
