From: Tianfei zhang <tianfei.zh...@intel.com>
In PAC N3000 card, there is one MAX10 chip in each card, and
all of the sensors are connected to MAX10 chip. To support multiple
cards in one server, we introducing a sensor device list under
intel_max10_device instead of a global list. On the other hand, we
using seperate intel_max10_device instance for each opae_adatper.
