usb: host: constify dev_pm_ops structures

Declare dev_pm_ops structures as const as they are only stored in the pm
field of a device_driver structure. This field is of type const, so
dev_pm_ops structures having similar properties can be declared const
too.

Size details after cross compiling the .o file for powerpc
architecture.

File size before:
   text    data     bss     dec     hex filename
   3183     372       0    3555     de3 drivers/usb/host/ehci-fsl.o

File size after:
   text    data     bss     dec     hex filename
   3275     280       0    3555     de3 drivers/usb/host/ehci-fsl.o
