Hi Arnd,

Trying to build the digicolor-usart driver when sysrq is disabled
results in a compile error:

drivers/tty/serial/digicolor-usart.c: In function 'digicolor_uart_console_write':
drivers/tty/serial/digicolor-usart.c:407:33: error: 'struct uart_port' has no member named 'sysrq'

Like a lot of other drivers, this one requires an #ifdef to avoid
accessing the sysrq field here. While looking into this, I noticed
that the case where sysrq support is enabled is also broken, because
the driver fails to set the SUPPORT_SYSRQ macro.

This patch hopefully fixes both, but I do not hardware to test if sysrq
is actually working now.

Unfortunately the hardware is not able to detect the BREAK condition, so it is 
not possible to support sysrq on this hardware. I'll send a patch removing 
sysrq reference.

Thanks for build testing and reporting.
