With the introduction of the streams API, the legacy embedded data
support has been removed. Pull out all code associated with the legacy
support.
Note that this driver has not been converted to use the streams API, so
embedded data will be unavailable.

The graph walk tries to follow all links, even if they are not between
pads. This causes a crash with, e.g. a MEDIA_LNK_FL_ANCILLARY_LINK link.
Fix this by allowing the walk to proceed only for MEDIA_LNK_FL_DATA_LINK
links.

Add support for Raspberry Pi CFE. The CFE is a hardware block that
contains:
- MIPI D-PHY
- MIPI CSI-2 receiver
- Front End ISP (FE)
The driver has been upported from the Raspberry Pi kernel commit
88a681df96 ("ARM: dts: bcm2712-rpi: Add i2c<n>_pins labels").

Add support for embedded data. This introduces two internal pads for pixel
and embedded data streams. As the driver supports a single mode only,
there's no need for backward compatibility in mode selection.
The embedded data is configured to be placed before the image data whereas
after the image data is the default.

With enable_streams and disable_streams, the driver for a device where
streams are not independently started and stopped needs to maintain state
information on streams that have been requested to be started. Do that
now.
In the future, a helper function in the framework is a desirable way to do
this instead.

Remove v4l2_subdev_enable_streams_api variable that was used to easily

This patch enables the streams API for V4L2 sub-device interface which

The len_routes field is used to tell the size of the routes array in
struct v4l2_subdev_routing. This way the number of routes returned from
S_ROUTING IOCTL may be larger than the number of routes provided, in case
there are more routes returned by the driver.
Note that this uAPI is still disabled in the code, so this change can
safely be done. Anyone who manually patched the code to enable this uAPI
must update their code.
