[media] v4l2-ctrls: use ptrs for all but the s32 type
Rather than having two unions for all types just keep 'val' and
'cur.val' and use the p_cur and p_new unions to access all others.
The only reason for keeping 'val' and 'cur.val' is that it is used
all over, so converting this as well would be a huge job.

You can also take the handler lock yourself:
mutex_lock(&state->ctrl_handler.lock);
- printk(KERN_INFO "String value is '%s'\n", ctrl1->cur.string);
+ pr_info("String value is '%s'\n", ctrl1->p_cur.p_char);
printk(KERN_INFO "Integer value is '%s'\n", ctrl2->cur.val);
mutex_unlock(&state->ctrl_handler.lock);
