[media] media: davinci: vpif_capture: move the freeing of irq and global variables...

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.
