Ulrich Hecht 49e2bcb7cf serial: sh-sci: fix break handling for sysrq ...

[ Upstream commit 87b8061bad ]

This fixes two issues that cause the sysrq sequence to be inadvertently
aborted on SCIF serial consoles:

- a NUL character remains in the RX queue after a break has been detected,
  which is then passed on to uart_handle_sysrq_char()
- the break interrupt is handled twice on controllers with multiplexed ERI
  and BRI interrupts
