Add system data for doing GPU callouts

The 2 GPU fault types (pgood & overtemp) are wired from
each GPU to a summary bit on the UCD90160.  If code
detects a summary bit on, it will need to read some GPIOs
on an IO expander (pca9552) to tell which actual GPU failed
in order to call it out.

This commit provides the data to know when to read the extra
GPIOs, and how those map to the specific faults and GPUs.
