Subject: [PATCH 1/7] perf: x86: intel: uncore: 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
   9361	    216	     88	   9665	   25c1	arch/x86/events/intel/uncore.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   9393	    184	     88	   9665	   25c1	arch/x86/events/intel/uncore.o
