HID: introduce helper to access hid_output_raw_report()

Add a helper to access hdev->hid_output_raw_report().

To convert the drivers, use the following snippets:

for i in drivers/hid/*.c
do
  sed -i.bak "s/[^ \t]*->hid_output_raw_report(/hid_output_raw_report(/g" $i
done

Then manually fix for checkpatch.pl
