Follow-ups

I test irtty_sir with a notebook with irda interface and ubantu 7.10.

For BF537-STAMP/BF533-STAMP/BF527-EZKIT, we can ircp a file to the notebook.

But failed to ircp a file from notebook to blackfin board, with error message

"Connecting...failed". In BF548-EZKIT, ircp donesn't work from both

blackfin board and notebook sides.

For BF527-EZKIT, when ircp a large file(eg:/bin/busybox) to notebook, it will

fail. The error message is as bellow:

root:/> ircp -r

ircp work well with PIO mode. DMA mode failed.

sir driver may change UART speed, even the last byte is sending bit by bit in

TSR register.

We now will change the speed until the last byte is sent out indeed.

Revert my previous commit.

We now use the sir_dev/irtty_sir/uart/bfin_serial drivers framework to monitor

the TX status.

We can transfer files now. So close it.
