media: rcar-csi2: Negotiate data lanes number

Browse source

Use the newly introduced get_mbus_config() subdevice pad operation to
retrieve the remote subdevice MIPI CSI-2 bus configuration and configure
the number of active data lanes accordingly.

In order to be able to call the remote subdevice operation cache the
index of the remote pad connected to the single CSI-2 input port.
