tty/sysrq: alpha: export and use __sysrq_get_key_op()
Export a pointer to the sysrq_get_key_op(). This way we can cleanly
unregister it, instead of the current solutions of modifuing it inplace.
Since __sysrq_get_key_op() is no longer used externally, let's make it
a static function.
This patch will allow us to limit access to each and every sysrq op and
constify the sysrq handling.
