staging: tidspbridge: remove unused code to handle iva_img

There is no way to specify the value of iva_img and since this code is not being used, remove it. This analysis resulted from a report by Chen Gang <gang.chen@asianux.com>, mentioning that the existing code was wrongly specifying the size to be copied.
