[RESEND,v2,00/19] CAMSS: Add SM8250 support

RESEND V2:
+ Cc: devicetree@vger.kernel.org on first patch

V2:
- Adds Tested-by Julian Grahsl as indicated.
- Fixes low-level noise checkpatch --strict
  I ended up having to push defines into static inlines for this.
- Adds Reviewed-by Robert Foss.
- Adds VFE/CSID fix for sdm845 as explicit additional sdm845 specific
  patch per Robert's suggestion.

I took the time then to test out on sdm845 to ensure the new patch breaks
nothing "./cam -c 1 --capture=1 --file=capture.raw" continues to produce
expected data.

This series is imported from excellent enabling work contributed by
Jonathan Marek which we have picked up in Linaro for the RB5 project.

The RB5 has a slightly different sku I think to Jonathan's platform -
QRB5165 in our case with a different version of LK the relevant bootloader
for the board.

As a result we needed to make some additional updates to the provided
patcheset, included here.

The most notable changes are:

- Addition of clocks.
- Addition of bandwidth settings.
- Representing the dependency on a VFE for a given CSID so that V4L
  subdevs will come out of reset right when poked.

A full tree which is bootable and capable of producing pixel data from the
imx577 main sensor is availble here, with this series being a sub-set of
the necessary patches on the SoC side only.
