the kernel ftrace can better help analyze the kernel running status. add some trace events to support TTM.
add trace events list:
ttm:ttm_bo_add_mem_to_lru ttm:ttm_bo_del_from_lru ttm:ttm_bo_move_mem ttm:ttm_bo_wait ttm:ttm_bo_evict ttm:ttm_bo_swapout ttm:ttm_bo_device_init ttm:ttm_bo_device_release ttm:ttm_bo_init_reserved ttm:ttm_bo_validate ttm:ttm_bo_release ttm:ttm_bo_mmap ttm:ttm_bo_vm_fault ttm:ttm_bo_vm_access ttm:ttm_shrink ttm:ttm_mem_global_reserve ttm:ttm_mem_global_free
