Subject: [PATCH v3 0/4] media: rkisp1: Fix IRQ related issues

These fix a few IRQ related issues I noticed when testing i.MX8MP. This
series, as of v3, is based on linux-media-stage, and does not include
i.MX8MP support, as that is not in upstream yet.

Changes in v3:
- Rebase on linux-media-stage
- Drop i.MX8MP support (which is a one line change) so that this can be
  based on upstream. I have still kept Adam's tested-by for
  imx8mp-beacon, as dropping the i.MX8MP support doesn't really affect the
  changes.
- Use ARRAY_SIZE() in patch 3
- Link to v2: https://lore.kernel.org/r/20231206-rkisp-irq-fix-v2-0-6ba4185eeb1f@ideasonboard.com

Changes in v2:
- New patch: "media: rkisp1: Drop IRQF_SHARED"
- Update "media: rkisp1: Fix IRQ handler return values" according to
  Laurent's comment.
- Drop "media: rkisp1: Fix IRQ handling due to shared interrupts"
- Update description for "media: rkisp1: Fix IRQ disable race issue"
- Link to v1: https://lore.kernel.org/r/20231205-rkisp-irq-fix-v1-0-f4045c74ba45@ideasonboard.com
