gpu: nvgpu: move linux configs from Kconfig file
Kstable branch is getting rid of all downstream patches. This also removes support for NVGPU build as kernel overlays will no longer be supported. In order to move towards a uniform out of tree build system, nvgpu must manage the CONFIGS present in Kconfig itself and stop relying on Kconfigs. A new file Makefile.linux.configs is created to house these configs temporarily. This file is included as part of the linux Makefile. Eventually the plan is to move towards using Makefile.shared.configs. This takes us one more step closer to having out of tree module building for NVGPU internal builds. With this change, kstable can still go ahead with building extmod builds for NVGPU. This also allows downstream builds to continue as in-tree builds as long as the overlays are set for the downstream kernels.
