PCI: Constify hotplug attribute_group structures 

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

File size before:
   text	   data	    bss	    dec	    hex	filename
    418	    160	      8	    586	    24a	drivers/pci/hotplug/rpadlpar_sysfs.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
    482	     96	      8	    586	    232	drivers/pci/hotplug/rpadlpar_sysfs.o
