Add the modified Bluetooth HID descriptor for the Dualshock 4.
By default, the Dualshock 4 sends controller data via report 1. Once an output
report is received the controller changes to sending data in report 17, which is
unmapped in the default descriptor. The mappings had to be moved to report 17 to
let the HID driver properly process the incoming reports.
