gpu: nvgpu: move platform_gk20a.h to linux

Move gk20a/platform_gk20a.h to linux specific directory as
common/linux/platform_gk20a.h since this file includes all linux specific
stuff

Fix #includes in all the files to include this file with correct path

Remove #include of this file where it is no more needed

Fix gk20a_init_sim_support() to receive struct gk20a as parameter
instead of receiving linux specific struct platform_device

NVGPU-316
