[PATCH 2/4] x86/power: hibernate: Fix W=1 build kernel-doc warnings

[Shivank Garg <shivankg@amd.com>]

Sample warnings generated with 'make W=1':
arch/x86/power/hibernate.c:47: warning: Function parameter or struct member 'pfn' not described in 'pfn_is_nosave'
arch/x86/power/hibernate.c:92: warning: Function parameter or struct member 'max_size' not described in 'arch_hibernation_header_save'

Add missing parameter documentation in hibernate functions to
fix kernel-doc warnings.
