accel/qaic: Add qaic driver to the build system

Now that we have all the components of a minimum QAIC which can boot and
run an AIC100 device, add the infrastructure that allows the QAIC driver
to be built.

+         Enables driver for Qualcomm's Cloud AI accelerator PCIe cards that are
+         designed to accelerate Deep Learning inference workloads.
+
+         The driver manages the PCIe devices and provides an IOCTL interface
+         for users to submit workloads to the devices.
+
+         If unsure, say N.
+
+         To compile this driver as a module, choose M here: the
+         module will be called qaic.
