[PATCH RESEND v6 0/5] Add CAMSS and IMX577 sensor support for Shikra EVK

Shikra EVK is based on the Qualcomm Shikra SoC.
It lacks a camera sensor in its default configuration.
This series adds CAMSS driver support, CCI definitions and enables
the 22-pin IMX577 sensor via CSIPHY1 through device tree overlays.

We have tested IMX577 Sensor on CCI1 with following commands:
- media-ctl --reset
- media-ctl -d /dev/media0 -V '"imx577 1-001a":0[fmt:SRGGB10/4056x3040 field:none]'
- media-ctl -d /dev/media0 -V '"msm_csiphy1":0[fmt:SRGGB10/4056x3040]'
- media-ctl -d /dev/media0 -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
- media-ctl -d /dev/media0 -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
- media-ctl -d /dev/media0 -l '"msm_csiphy1":1->"msm_csid0":0[1]'
- media-ctl -d /dev/media0 -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video0

Used following tools for the sanity check of these changes.

  (Shikra) and VFE+CDM+OPE read+OPE write (QCM2290/Agatti); add
  per-entry descriptions naming each SID (Krzysztof, Bryan)
- Rename shikra-cqm-evk-imx577-camera overlay to
  shikra-cqm-cqs-evk-imx577-camera, shared by both CQM and CQS EVK
  boards which use the same PM4125 PMIC and camera supply rails (Bryan)
