ENGR00178951-2 SYSRQ: enable CONFIG_MAGIC_SYSRQ by default

SYSRQ is very useful for kernel debug thus enable it by default.

SYSRQ support serial port, we can send the command via minicom:

CTRL A + F (send BRK) + T: to dump the task information

Enable SYSRQ by default will not involve any performance drop
