[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.
