[PATCH] drivers:staging:ti-st: fix kim platform device id

[Savoy, Pavan]

Greg,

Any updates?
Please ... Please find some time to have a look at it!!

Alan,

Please have a look at it too. I've dealt with most of the comments, device context has been provided, spin-locks have been reviewed and documented multiple devices also can be easily supported if required.
