Subject: [PATCH] Fix input not responding

Pad mode set was missing that cause a few games which queries for an
analog-type controller to fail or causes no inputs at all.

This also change the "standard" input type to behave like one, which
means it does not have rumble or analog inputs. A required input type is
necessary to set the desired input effects.

Probably needs some cleanup but it works for now.

Fixes https://github.com/libretro/pcsx_rearmed/issues/161 and probably
other input related issues.
