gpu: nvgpu: remove kind map inheritance

Currently, the kind map initialization inherits from earlier
chips' kind map definitions and simply adds on newly supported
features. This is dangerous as changes in older architectures
may affect newer architectures in unpredictable ways.

This patch removes inheritance between subsequent architectures'
kind map initializations.
