It makes more sense to have a list of the ioctls that need power than
the other way around. This patchset takes care of this.

It also fixes one error in the PM logic introduced in a recent patchset.

To support CI I have included two patches that are in uvc/next but not
in media-committer:
media: uvcvideo: Refactor uvc_queue_streamon
media: uvcvideo: Refactor uvc_v4l2_compat_ioctl32
Do not review them again.

To avoid conflicts I am adding the fop patchset as well:
media: uvcvideo: Use vb2 ioctl and fop helpers
media: uvcvideo: Remove stream->is_streaming field
Please review them in https://patchwork.linuxtv.org/project/linux-media/list/?series=15664

Changes in v2. Thanks HdG:
- Rebase fop
- CodeStyle
- Refactor SEND_INITIAL to avoid lis_del()
- Squash "invert PM logic" and "unless is needed"
- Link to v1: https://lore.kernel.org/r/20250528-uvc-grannular-invert-v1-0-d01581f9cc25@chromium.org
