gpu: nvgpu: SEC2 RTOS support s/w init

-Created struct nvgpu_sec2 to hold members
 related to SEC2-RTOS ucode support in header file
 sec2.h
-Created nvgpu_sec2 variable under struct gk20a.
-Created NVGPU_SUPPORT_SEC2_RTOS enable flag
 to enable SEC2 RTOS support.
-Defined method nvgpu_init_sec2_support() to
 init SEC2 RTOS support by performing s/w setup like
 mutex-init, sequence-init & add support
 for remove_support.
-Defined method nvgpu_sec2_destroy() to deinit
 SEC2 RTOS support.
-Added nvgpu_init_sec2_support()/nvgpu_sec2_destroy()
 as part gk20a_finalize_poweron()/gk20a_prepare_poweroff()
 sequence based on NVGPU_SUPPORT_SEC2_RTOS enable flag
-Assigned g->sec2->flcn to point to g->sec2_flcn to access
 falcon.
-Made Makefile changes to include sec2.c to build
