[PATCH] pipeline: rkisp1: Fix vblank delay

[Kieran Bingham]

Quoting Paul Elder (2025-04-21 07:49:59)
> The vblank delay for delayed controls was incorrectly hardcoded to 1.
> Get it from the camera sensor properties instead.
> 
> Fixes: f72c76eb6e06 ("rkisp1: Honor the FrameDurationLimits control")
