In kernel v5.11 the rkisp1 uapi had changed to support
different hardware versions. See [1]
This patchsets updates the uapi header and adds support
to hardware version 10 only.
In the future we want to add support to version V12.
See revisions documentation at [2].

The patchset is based on v8 of the 3 IPA isolation patchsets.

[1] https://patchwork.kernel.org/project/linux-media/list/?series=419197

[2] https://www.kernel.org/doc/html/latest/admin-guide/media/rkisp1.html?highlight=revisions#revisions

Changes from v1:
- compilation fix in patch 3 that I forgot to update in first version
- typo fixes
- in patch 2, if 'configure' of the rkisp1 IPA fails return -EINVAL
- in patch 3, if hw revision is not supported, return -ENODEV

Dafna Hirschfeld (3):
  libcamera: media_device: add hwRevision method
  src: rkisp1: return error from ipa's configure method if it fails
  ipa: rkisp1: update the uapi to the latest kernel version
