Subject: [PATCH] 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 'seq' not described in 'rdt_bit_usage_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.

Fixes: e651901187ab ("x86/intel_rdt: Introduce "bit_usage" to display cache allocations details")
Fixes: fa8f711d2f14 ("x86/resctrl: Pass configuration type to resctrl_arch_get_config()")
Fixes: 49f7b4efa110 ("x86/intel_rdt: Enable setting of exclusive mode")
Fixes: d9b48c86eb38 ("x86/intel_rdt: Display resource groups' allocations' size in bytes")
Reported-by: kernel test robot <[email protected]>
Closes: https://lore.kernel.org/oe-kbuild-all/[email protected]/

First three warnings originally reported by kernel test robot are not
fixed here since they have already been addressed in [1] and merged
into x86/urgent.
