I2C transfer functions return number of successful operations (on success).
Do not return the received positive return code but instead return 0 on
success. The users of write_reg function already use this logic.

Use v4l2_find_nearest_size instead of a driver specific function to find
nearest matching size.

The device node obtained with of_graph_get_next_endpoint() should be
released by calling of_node_put(). But it was not released when
v4l2_fwnode_endpoint_parse() failed.
This change moves the of_node_put() call before the error check and
fixes the issue.

Add suport for standard integer menu V4L2_CID_LINK_FREQ control.
The CSI2 link frequency value is specific for each sensor mode so the
sensor mode structure is extended to add this. The control is made
read-only and its value is updated when the sensor mode is changed -
on set_format.

Switch users of the v4l2_of_ APIs to the more generic v4l2_fwnode_ APIs.
Async OF matching is replaced by fwnode matching and OF matching support
is removed.
