dev_pm_ops is never modified, so mark it const to allow the compiler to
put it in read-only memory.

Before:
   text    data     bss     dec     hex filename
   2457    1668     256    4381    111d drivers/xen/platform-pci.o

After:
   text    data     bss     dec     hex filename
   2681    1444     256    4381    111d drivers/xen/platform-pci.o
