Quake 3 has an obvious use for motion controls. What would you want to do with motion controls in hellblade? I can't think of anything that would make any sense. If you just want to be able to use touch controls to play it, you can do that. There's just nothing to actually point or swing around or anything, all combat animations are canned and the enemy responses are fixed animation too and reliant on the characters fixed animations to trigger. So they would have to completely recreate combat from the ground up, and the combat isn't even a focus of the game. It's just not in any way a motion controls kind of game.
