media: Documentation: BT.601 is not a bus

Browse Source 
BT.601 is not actually a bus specification, leaving parallel bus without a
specification to refer to. Fix this.

===========================================
V4L2 supports various devices that transmit and receive pixel data. Examples of
these devices include a camera sensor, a TV tuner and a parallel or a CSI-2
receiver in an SoC.

Parallel and BT.656
^^^^^^^^^^^^^^^^^^^
`BT.601`_ and `BT.656`_ are the most common parallel busses.
The parallel and `BT.656`_ buses transport one bit of data on each clock cycle
per data line. The parallel bus uses synchronisation and other additional
signals whereas BT.656 embeds synchronisation.
