hvc_console: Escape magic sysrq key
The ctrl-o (^O) is a common control key used by several applications,
such as vim, but hvc_console uses ^O as the magic-sysrq key. This
commit allows users to send ^O to applications by pressing ^O twice
in succession.
To implement this, this commit introduces a check if ^O is pressed
again if the sysrq_pressed variable is already set. In this case,
clear sysrq_pressed state and flip the ^O character to the tty. (The
old behavior has always set "sysrq_pressed" if ^O has been entered,
and it has not flipped the ^O character to the tty.)
