Fixed bug 5445 - Incorrect Switch Pro Controller face buttons when SDL_HINT_GAMECONTROLLER_USE_BUTTON_LABELS disabled

jibb

I'm testing with DualShock 4, DualSense, Switch Pro Controller, and PowerA Switch Controller.

I'm using the standard mapping file from here:
https://raw.github.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt

With SDL_HINT_GAMECONTROLLER_USE_BUTTON_LABELS turned off (set to "0") I expect the button positions to be the same on all devices, based on Xbox controller button naming (eg SDL_GameControllerGetButton(g, SDL_CONTROLLER_BUTTON_Y) gives me whether the North face button is pressed).

However, the Switch Pro Controller layout is wrong (matching labels rather than positions, so X and Y are swapped and A and B are swapped). And with the PowerA controller the East and West buttons are correct, but the North and South buttons are swapped instead.

Also seeing this on 2.0.14. This is most likely a regression, since we weren't seeing this on an earlier SDL version.

I suspect it might be caused by this commit:
a569b21188 (diff-da9344d94c66b8c702a45e7649f412039f08bba83bd82de33f5c80ea9c8c39d5)

It seems like both the HIDAPI driver and SDL_gamecontroller.c will try to swap the buttons if the hint is set to 0, causing the button remap to cancel out.
