headers/deps: USB: Optimize <linux/usb/ch9.h> dependencies, remove <linux/device.h>

Browse source 
The <linux/usb/ch9.h> header is used over 1,400 times in a typical distro
build, but few of its users actually need the full <linux/device.h> header.

          --------------------------------------------------------------------
          | Combined, preprocessed C code size of header, without line markers,
          | with comments stripped:
          -------------------------
  before: | #include <linux/usb/ch9.h>              | LOC:  7,078 | headers:  172
   after: | #include <linux/usb/ch9.h>              | LOC:    812 | headers:   38

Remove it and add it to the places that need it.
