HID: bt hidp: send Output reports using SET_REPORT on the Control channel

The current implementation of hidp_output_raw_report() relies only on
the Control channel even for Output reports, and the BT HID
specification [1] does not mention using the DATA message for Output
reports on the Control channel (see section 7.9.1 and also Figure 11:
SET_ Flow Chart), so let us just use SET_REPORT.

This also fixes sending Output reports to some devices (like Sony
Sixaxis) which are not able to handle DATA messages on the Control
channel.

Ideally hidp_output_raw_report() could be improved to use this scheme:
  Feature Report -- SET_REPORT on the Control channel
  Output Report  -- DATA on the Interrupt channel
for more efficiency, but as said above, right now only the Control
channel is used.
