media: v4l2-subdev: Drop .set_mbus_config() operation

Browse source 
The .set_mbus_config() operation is deprecated, and nothing in the
kernel uses it. Drop it.

* How to use the V4L2_MBUS_* flags:
* Flags are defined for each of the possible states and values of a media
* bus configuration parameter. One and only one bit of each group of flags
* shall be set by the users of the v4l2_subdev_pad_ops.get_mbus_config and
* v4l2_subdev_pad_ops.set_mbus_config operations to ensure that no
* conflicting settings are specified when reporting and setting the media bus
* configuration with the two operations respectively. For example, it is
* invalid to set or clear both the V4L2_MBUS_HSYNC_ACTIVE_HIGH and the
* shall be set by the users of the v4l2_subdev_pad_ops.get_mbus_config
* operation to ensure that no conflicting settings are specified when
* reporting the media bus configuration. For example, it is invalid to set or
* clear both the V4L2_MBUS_HSYNC_ACTIVE_HIGH and the
* V4L2_MBUS_HSYNC_ACTIVE_LOW flag at the same time. Instead either flag
* V4L2_MBUS_HSYNC_ACTIVE_HIGH or flag V4L2_MBUS_HSYNC_ACTIVE_LOW shall be
* set. The same is true for the V4L2_MBUS_CSI2_1/2/3/4_LANE flags group: only
* one of these four bits shall be set.
* V4L2_MBUS_HSYNC_ACTIVE_HIGH or flag V4L2_MBUS_HSYNC_ACTIVE_LOW shall be set.
* The same is true for the V4L2_MBUS_CSI2_1/2/3/4_LANE flags group: only one
* of these four bits shall be set.
*
* TODO: replace the existing V4L2_MBUS_* flags with structures of fields
* to avoid conflicting settings.
