[PATCH 08/12] media: ipu3-cio2: Add supported_sensors parameter to cio2_bridge_init()

[Hans de Goede <hdegoede@redhat.com>]

Add a supported_sensors parameter to cio2_bridge_init(), so that
cio2_bridge_init() can be used with other bridges which have been
tested with / support a different set of sensors.

This is a preparation patch for making the cio2-bridge code more generic
so that it can be shared with the atomisp driver.
