accel/qaic: Add AIC080 support

Browse Source 
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.
