[media] docs-rst: Make the CSI-2 bus initialisation documentation match reality
Update the CSI-2 bus documentation to tell that the LP-11 mode is not
mandatory as there are transmitters that cannot be explicitly set to LP-11
mode. Instead, say that this what the transmitter drivers shall do if
possible.
