tty: remove use of __devexit
CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.

tty/serial/ar933x_uart: fix baud rate calculation
The UART of the AR933x SoC implements a fractional divisor
for generating the desired baud rate.
The current code uses a fixed value for the fractional
part of the divisor, and this leads to improperly
calculated baud rates:
baud scale step real baud diff
300 5207* 8192 17756 17456 5818.66%
600 2603* 8192 35511 34911 5818.50%
1200 1301* 8192 71023 69823 5818.58%
2400 650* 8192 11241 8841 368.37%
4800 324* 8192 22645 17845 371.77%
9600 161 8192 9645 45 0.46%
14400 107 8192 14468 68 0.47%
19200 80 8192 19290 90 0.46%
28800 53 8192 28935 135 0.46%
38400 39 8192 39063 663 1.72%
57600 26 8192 57870 270 0.46%
115200 12 8192 120192 4992 4.33%
230400 5 8192 260417 30017 13.02%
460800 2 8192 520833 60033 13.02%
921600 0 8192 1562500 640900 69.93%
After the patch, the integer and fractional parts of the
divisor will be calculated dynamically. This ensures that
the UART will use correct baud rates:
baud scale step real baud diff
300 6 11 300 0 0.00%
600 54 173 600 0 0.00%
1200 30 195 1200 0 0.00%
