[PATCH v2 5/8] dt-bindings: display: vop2: Add rk3576 support

[Andy Yan]

From: Andy Yan <andy.yan at rock-chips.com>

Add vop found on rk3576, the main difference between rk3576 and the
previous vop is that each VP has its own interrupt line.

Signed-off-by: Andy Yan <andy.yan at rock-chips.com>

---

Changes in v2:
- describe constraint SOC by SOC, as interrupts of rk3576 is very
  different from others
- Drop Krzysztof's Reviewed-by, as this version changed a lot.

Changes in v1:
- ordered by soc name
- Add description for newly added interrupt
