serial: Fix sh-sci break interrupt/sysrq handling.
The sh-sci sci_br_interrupt() handler was failing to call in to uart_handle_break(), which was something that only the SH-3 path was doing, fix that up. Additionally, SUPPORT_SYSRQ seems to have moved down too far, move it back to the top so uart_handle_break() and friends aren't no-ops. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
