[PATCH 1/4] misc: rtsx_usb: Constify struct usb_device_id

[Rikard Falkeborn]

rtsx_usb_usb_ids is never modified and can therefore be made const to
allow the compiler to put it in read-only memory.

Before:
   text    data     bss     dec     hex filename
  21513    4160     128   25801    64c9 drivers/misc/cardreader/rtsx_usb.o

After:
   text    data     bss     dec     hex filename
  21673    4000     128   25801    64c9 drivers/misc/cardreader/rtsx_usb.o
