Subject: reboot: rename now misleading __hw_protection_shutdown symbols
X-Git-Tag: v6.15-rc1~80^2~49

reboot: rename now misleading __hw_protection_shutdown symbols

The __hw_protection_shutdown function name has become misleading since it
can cause either a shutdown (poweroff) or a reboot depending on its
argument.

To avoid further confusion, let's rename it, so it doesn't suggest that a
poweroff is all it can do.
