cpufreq: intel_pstate: constify 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
  15197    2552      40   17789    457d drivers/cpufreq/intel_pstate.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  15261    2488      40   17789    457d drivers/cpufreq/intel_pstate.o
