platform/chrome: cros_ec_lpc: Remove EC panic shutdown timeout 

JIRA: https://issues.redhat.com/browse/RHEL-33550

commit f2d4dced9a584612b25adb559c1350243d2bb544
Author: Rob Barnes <robbarnes@google.com>
Date: Mon, 07 Aug 2023 10:39:16 +0000

Remove the 1 second timeout applied to hw_protection_shutdown after an
EC panic. On some platforms this 1 second timeout is insufficient to
allow the filesystem to fully sync. Independently the EC will force a
full system reset after a short period. So this backup timeout is
unnecessary.
