[media] media: davinci: vpif_display: move the freeing of irq and global variables to remove()
Ideally the freeing of irq's and the global variables needs to be done in the remove() rather than module_exit(), this patch moves the freeing up of irq's and freeing the memory allocated to channel objects to remove() callback of struct platform_driver.
