Subject: [PATCH 2/5] Input: xpad - add init packet for Hori and Titanfall 2 pads

Without sending this packet, the Titanfall 2 pad (0x0e6f:0x0165)
continuously attempts to handshake with the PC and never sends
any input reports.

The Hori gamepad (0x0f0d:0x0067) analog sticks don't work if
this isn't sent, though other buttons do work without it.
