recover from davinci i2c time out conditions

This patch address several timeout problems that have been reported like the one below. The kernel must be robust enough to handle such timeouts without having to reboot the system manually. This patch has only been tested on a DM355 hence extensive testing is required on other davinci's as well. Hoping someone will take that up.

Hi Kevin,

When we do a video loopback with MT9T031, we get i2c timeouts when application is killed using Cntrl C. Is it being addressed in any of the patches? We had the same issue with TI LSP releases (1.20, 2.00, 2.1o etc).
The board has to be rebooted to recover from this.
