lm4: add warm reboot key combination
Added a warm reboot key combination that resets the CPU while preserving
RAM contents. This will be helpful in debugging CPU/OS hard hangs since
in conjunction with PSTORE_CONSOLE in the kernel, the kernel log
messages from the previous boot will be preserved.
BUG=chrome-os-partner:12780
TEST=reboot the system using alt-volume_up-r key combination. Upon
rebooting, check pstore contents with "cat /dev/pstore/console-ramoops"
and ensure that they are same as dmesg from the previous boot.
