HID: playstation: set default DualShock4 BT poll interval to 4ms.
The poll interval for DualShock4 in Bluetooth mode is adjustable through the main output report. Configure it to 4ms, which is similar to USB. Signed-off-by: Roderick Colenbrander <roderick.colenbrander@sony.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
