[PATCH v4 6/6] power: remove unused auto-detection uncore

[Huisong Li <lihuisong@huawei.com>]

Applications need to set uncore environment first by calling the API
rte_power_set_uncore_env, please see the commit 3b3af56d3c9c ("power:
fix uncore configuration").

Now, rte_power_set_uncore_env() supports automatic detection of uncore
drivers, the automatic detection environment code can be deleted.
