gpu: nvgpu: Use noinline_for_stack to avoid GCOV build break
If code coverage is enabled on GCC 4.7, the kernel build fails in
gk20a_init_kind_attr() since GCC decides to inline almost everything in
this file into it, leading to a massive stack frame with over kilobyte's
worth of temporary variables generated by gcov, leading to this error:
kind_gk20a.c: In function 'gk20a_init_kind_attr':
kind_gk20a.c:424:1: error: the frame size of 1232 bytes is larger than
1024 bytes [-Werror=frame-larger-than=]
(Just removing the inline keyword doesn't work, as GCC still decides to
inline it, so noinline_for_stack is actually required.)
