gpu: nvgpu: Move secure_alloc to struct gk20a

Move the function pointer for VPR page allocation to struct gk20a
and use it from there. At the same time remove secure_page_alloc
pointer and add a direct call to it in probe.

Move platform_tegra.h as tegra/linux/platform_gk20a_tegra.h, as it's
only declaring functions defined in platform_gk20a_tegra.c to other
files in the same directory.
