[dpdk-dev] [PATCH 08/12] raw/ifpga_rawdev/base: introducing sensor APIs

[Rosen Xu <rosen.xu@intel.com>]

From: Tianfei Zhang <tianfei.zhang@intel.com>

Introducing sensor APIs to PMD driver for PAC N3000 card.

Those sensor APIs:
1. opae_mgr_for_each_sensor()
2. opae_mgr_get_sensor_by_name()
3. opae_mgr_get_sensor_by_id()
4. opae_mgr_get_sensor_value_by_name()
5. opae_mgr_get_sensor_value_by_id()
6. opae_mgr_get_sensor_value()
