Change 30639 by marcel at marcel_nfs on 2003/05/05 15:04:42

	Actually remove a couple more device flags we don't use:
	COM_NOFIFO, COM_ST16650A, COM_TI16754 and COM_FIFOSIZE
	are kludges we don't need, now that we probe the FIFO size
	and we also don't want because we should probe the UART
	for additional features. COM_NOPROBE was not used before
	I started axing. COM_NOSCR was mainly used to kludge
	around phase ordering. We don't need to access the
	scratch pad, unless we need (want) to destinguish between
	8250 and 16450. This depends on the existence of a FIFO
	and should not be done unconditionally.
