accel/qaic: Add AIC080 support

Add basic support for the new AIC080 product. The PCIe Device ID is
0xa080. AIC080 is a lower cost, lower performance SKU variant of AIC100.
From the qaic perspective, it is the same as AIC100.

+Overview
+========
+
+The Qualcomm Cloud AI 80/AIC080 family of products are a derivative of AIC100.
+The number of NSPs and clock rates are reduced to fit within resource
+constrained solutions. The PCIe Product ID is 0xa080.
+
+As a derivative product, all AIC100 documentation applies.
