Improve the documentation by specifying that the instructions
are related to the i.MX6Q sabreauto variant.
This avoids confusion if someone follows these steps on a i.MX6DL
sabreauto, which has different numbering on the I2C bus and
I2C muxes.

In the i.MX6Q sabreauto pipeline example, it is better to provide
a real example for the output format, so do it just like in the
previous lines for consistency.

The i.MX6DL sabreauto has different numbering on the I2C bus and
I2C muxes compared to the i.MX6Q as shown in the kernel log below:
[ 5.159423] imx-media: ipu1_csi0_mux:5 -> ipu1_csi0:0
[ 5.164618] imx-media: ipu1_csi1_mux:5 -> ipu1_csi1:0
[ 5.169953] imx-media: adv7180 4-0021:0 -> ipu1_csi0_mux:4
To avoid confusion, add an entry that shows how to setup the links and
configure the pads that are specific to the i.MX6DL sabrea
