Konsta Hölttä 4a7a6c0839 gpu: nvgpu: evaluate srctree.nvgpu immediately ...

The definition of srctree.nvgpu for external modules is specified as a
function of $(MAKEFILE_LIST). This variable gets extended also when
files are included, so any include directives in the makefile affect the
path because srctree.nvgpu is assigned with "?=" which is lazy like "=".

To avoid problems with the lazy init, use ":=" surrounded with an
explicit check to initialize srctree.nvgpu only when undefined.
