Fix defines all over the place.

[blockhead100]

There are lots of #define all over like in nv-gpu-info.h where there is a #define NV_MAX_DEVICES 32 and in nvlimits.h it defines it again.
Should this be fixed?

In general, nvlimits.h is intended to be the source of truth: it should have no dependencies on anything else.

Sure, it seems reasonable to me to delete NV_MAX_GPUs and have its current users include nvlimits.h and use NV_MAX_DEVICES instead.

Do you have other examples? We probably should handle on a case-by-case basis.
