android: fiq_debugger: restrict access to critical commands.
Sysrq must be enabled via /proc/sys/kernel/sysrq as a security
measure to enable various critical fiq debugger commands that
either leak information or can be used as a system attack.
Default disabled, this will leave the reboot, reset, irqs, sleep,
nosleep, console and ps commands. Reboot and reset commands
will be restricted from taking any parameters. We will also
switch to showing the limited command set in this mode.
