Subject: [PATCH 2/7] perf: x86: intel: uncore_nhmex: constify attribute_group structures.

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by 'uncore.h' work with const
attribute_group. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   8236	   5992	      1	  14229	   3795	x86/events/intel/uncore_nhmex.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   8620	   5608	      1	  14229	   3795	x86/events/intel/uncore_nhmex.o
