Bug #17637: /dev/ttySAC1 is always opened in read-only mode

More info:
1) /dev/ttySAC1 is a serial port used on samsung s3c2440 (e.g. openmoko
	freerunner):

$ stat /dev/ttySAC1
File: `/dev/ttySAC1'
Size: 0 Blocks: 0 IO Block: 4096 character special file
Device: ch/12d Inode: 161 Links: 1 Device type: cc,41
Access: (0660/crw-rw----) Uid: ( 0/ root) Gid: ( 20/ dialout)
Access: 2010-10-19 01:23:13.893489000 +0300
Modify: 2010-10-18 20:21:22.089934000 +0300
Change: 2010-10-18 20:21:22.089934000 +0300

2) I think the problem is in gpsd_classify(). It assumes that
	all serial ports have major number of 4. It even links to
	ftp://ftp.kernel.org/pub/linux/docs/device-list/devices-2.6+.txt
	as a reference. However, that file nowadays lists also

204 char Low-density serial ports
0 = /dev/ttyLU0 LinkUp Systems L72xx UART - port 0
1 = /dev/ttyLU1 LinkUp Systems L72xx UART - port 1
2 = /dev/ttyLU2 LinkUp Systems L72xx UART - port 2
3 = /dev/ttyLU3 LinkUp Systems L72xx UART - port 3
4 = /dev/ttyFB0 Intel Footbridge (ARM)
5 = /dev/ttySA0 StrongARM builtin serial port 0
6 = /dev/ttySA1 StrongARM builtin serial port 1
...

The patch adds 204 to the list of recognized major numbers.
