8250 Serial Driver: revert extra IRQ flag definition patch
As Russell pointed out, original patch will break some serial configurations because of the dependency of the <asm/serial.h> header file. Revert it first and try to find out other solution later Cc: Javier Herrero <jherrero@hvsistemas.es> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Russell King <rmk+lkml@arm.linux.org.uk> Signed-off-by: Bryan Wu <cooloney@kernel.org>
