Revert "Added joystick config to pwswd-gcw0.conf"

This reverts commit 2b840c124b4045321aa9d940b6487a8020348f96.
Revert "Add support for handling joystick buttons and hat events"

This was introduced so that the shortcuts would still work when the
joystick mode of linkdev is used.

However, in recent OpenDingux, evdev is only used to output the events
generated by "gpio-keys", bypassing linkdev. As a result, pwswd sill
receives key events when linkdev is in joystick mode.

This reverts commit 69d9f4c2b093819df8948c0d6435090045d6be36.
