[PATCH v2 2/4] PM: hibernate: Define and parse hibernate=relaxed_memmap parameter

[Marco Scardovi <scardracs@disroot.org>]

Define the 'hibernate_relaxed_memmap' global variable and parse the
'relaxed_memmap' option under the 'hibernate=' kernel boot parameter.
This enables users to relax E820 memory map integrity checks during resume.
