raw/ifpga/base: support multiple cards

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 separate intel_max10_device instance for each opae_adatper.

Add mutex lock on do_transaction() function for SPI driver to avoid
race condition.
