x86/resctrl: Fix remaining kernel-doc warnings

The kernel test robot reported kernel-doc warnings here:

  arch/x86/kernel/cpu/resctrl/rdtgroup.c:915: warning: Function parameter or member 'of' not described in 'rdt_bit_usage_show'
  arch/x86/kernel/cpu/resctrl/rdtgroup.c:915: warning: Function parameter or member 'seq' not described in 'rdt_bit_usage_show'

  arch/x86/kernel/cpu/resctrl/rdtgroup.c:1370: warning: Function parameter or member 's' not described in 'rdtgroup_size_show'
  arch/x86/kernel/cpu/resctrl/rdtgroup.c:1370: warning: Function parameter or member 'v' not described in 'rdtgroup_size_show'

The first two functions are missing an argument description while the
other three are file callbacks and don't require a kernel-doc comment.
