Hi all

This set contains a number of fixes to the Mali-C55 pipeline handler that have
been in our development tree whilst we worked on the IPA module - they weren't
posted before because things have been in quite a lot of flux, but now that the
IPA patchset is itself public it's time for these to go upstream too.

Thanks
Dan

Prior changelogs (which are now on the patches themselves)

v3-v4: based on the v6 of the kernel driver [1]
- Collecting tags
- Added patches correcting the representation of input/output formats (#10)
- Added a patch enabling links between resizer and capture device, which in the
  latest version of the kernel driver are mutable (#11)
- Added the ScalerCrop patches back in (#12 and #13)

v2->v3:
- Collect additional tags
- Add 3 patches to add Mali C55 media bus formats to libcamera and to fix
  20-bit format propagation to CSI-2 to ISP

v1->v2
- Drop ScalerCrop and scaler handling
- Limit ISP input size to 640x480
- Adjust the RAW configuration stride and image size to 4 bytes
