usb: dwc3: drd: File headers are not doc headers

Demote drd.c's file header to a standard comment block.

Fixes the following W=1 build warnings:

 drivers/usb/dwc3/drd.c:20: warning: Function parameter or member 'dwc' not described in 'dwc3_otg_disable_events'
 drivers/usb/dwc3/drd.c:20: warning: Function parameter or member 'disable_mask' not described in 'dwc3_otg_disable_events'
