drm/ttm: Replace multiple booleans with flags in device init

Browse Source 
Multiple consecutive boolean function arguments are usually not very

Replace the ones in ttm_device_init() with flags with the additional
benefit of soon being able to pass in more data with just a one off
code base churning cost.
