media: subdev: Support privacy led in v4l2_subdev_enable/disable_streams()

Browse source

We support camera privacy leds with the .s_stream() operation, in
call_s_stream(), but we don't have that support when the subdevice
implements .enable/disable_streams() operations.

Add the support by enabling the led when the first stream for a
subdevice is enabled, and disabling the led then the last stream is
disabled.
