The changeset introduces an initial version of long awaited CSIPHY
devices, which is agreed to be used along with any new added CAMSS
platform support.

Any platform and board dts changes are not intended to be added into
the series, however the changeset includes sm8250.dtsi and RB5 vision
mezzanine dtso changes for reference and testing purposes.

The changeset is based on top of this one:
* https://lore.kernel.org/all/20250513142353.2572563-1-vladimir.zapolskiy@linaro.org/

The changeset includes a new generic CSIPHY dt bindings evolved from
an RFC one, which has been submitted under phy folder originally:
* https://lore.kernel.org/all/20250513143918.2572689-1-vladimir.zapolskiy@linaro.org/

Known limitations:
* There is no regression with old dt bindings, however under the new
  scheme of CSIPHY to CSID link a TPG may not work expectedly,
* to preserve backwards compatibility all CSIPHY resources are taken
  from CAMSS device tree node, and it's a subject for a future change.
