In the general case, a driver doesn't know which of system shutdown or
reboot is the better action to take to protect hardware in an emergency
situation. For this reason, hw_protection_shutdown is going to be
removed in favor of hw_protection_trigger, which defaults to shutdown,
but may be configured at kernel runtime to be a reboot instead.
The ChromeOS EC situation is different as we do know that shutdown is
the correct action as the EC is programmed to force reset after the
short period, thus replace hw_protection_shutdown with
__hw_protection_trigger with HWPROT_ACT_SHUTDOWN as argument to
maintain the same behavior.
No functional change.
