[PATCH] usb: dwc3: pci: constify dev_pm_ops structures.

[Arvind Yadav]

dev_pm_ops are not supposed to change at runtime. All functions
working with dev_pm_ops provided by <linux/device.h> work with const
dev_pm_ops. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   2707	    456	      0	   3163	    c5b	drivers/usb/dwc3/dwc3-pci.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   2899	    264	      0	   3163	    c5b	drivers/usb/dwc3/dwc3-pci.o
