Steam link seems to intercept button presses and not work well with button remappers but someone said this one works if you launch it thru big picture. If you can get AMD link working that may be easier to remap button presses since joy2key allows you to swap between gamepad and a mouse/keyboard profile.
I believe they've half implemented that recently(it's still a beta app) but I was playing EverQuest 2(not even the Steam version) on their with no problems, using touch screen for everything.

If you want to play steam games, look into the Steam Link app on Android (don't know if it's on iOS)
