gpu: nvgpu: Move gk20a.c to os/linux

Browse Source 
gk20a.c is used only in Linux build. It's in theory common code, but
in practice implements OS specific policies. Also implement
os/posix/gk20a.c to implement gk20a_init_gpu_characteristics(),
gk20a_get() and gk20a_put() which are called from common code.
