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
