PM: sleep: Add pm_debug_messages kernel command line option
Debug messages from the system suspend/hibernation infrastructure
are disabled by default, and can only be enabled after the system
has boot up via /sys/power/pm_debug_messages.
This makes the hibernation resume hard to track as it involves system
boot up across hibernation. There's no chance for software_resume()
to track the resume process, for example.
Add a kernel command line option to set pm_debug_messages during
boot up.
