Rewrote NS16550 TX interrupt processing to use termios for the buffer and manage the interrupt sources like the other drivers. This let use remove the ns16550_flush() routine.

5	General
6	=======
7
8	+ Hardware flow control is not currently supported. Some of the chip
9	drivers (in particular the z8530) have support for hardware flow control
10	but this has not been tested in the libchip context. There will need
11	to be a way to totally disabled hardware flow control which is not
12	currently in this.
13
14	+ "ulClockSpeed" configuration item field to become a pointer to a table
15	of chip specific information. For example, the z8530 should specify
16	clock speed and clock divisor setting.
17
18	+ A termios structure should be included to specify the initial settings.
19	Right now all drivers default to 9600, 8N1.
20
21	+ Need to switch to passing pointers rather than a minor number to
22	functions which are strictly internal to each chip driver. This
23	should be a performance win.
24
25	MC68681
26	=======
27
28	+ Works interrupt and polled.
29
30	+ Hardware flow control not included.
31
32	NS16650
33	=======
34
35	+ Not tested in libchip context. Based on Radstone PPC2 driver which worked
36	well.
37
38	+ Interrupt code has been reworked to not use ring buffer and may be broken
39	as it has not been tested since this was done.
40
41	+ Missing set attributes function.
42
43	Z85C30
44	======
45
46	+ Works polled and interrupt.
47
48	+ Hardware flow control included but is currently disabled.
49
50	+ Needs to support mode where more specific vectors are generated.
