Magic SysRq key is not working for OMAP on new serial
console ttyOx because SUPPORT_SYSRQ is not defined
for omap-serial.

This patch defines SUPPORT_SYSRQ in omap-serial and
enables handling of Magic SysRq character.

Further there is an issue of losing first break character.
Removing the reset of the lsr_break_flag fixes this issue.
