[PATCH] kernel/reboot: document function parameter

[Matti Vaittinen]

The hw_failure_emergency_poweroff() has been documented using kernel
doc. The documentation omits description of the function parameter
'int poweroff_delay_ms' - which seems like self-explatonary.

However, the build bot is nagging about the missing parameter
documentation, so add the trivial documentation to shut the bot up.
