[PATCH] media: imx: Constify static struct v4l2_m2m_ops

[Kieran Bingham]

Quoting Rikard Falkeborn (2021-10-12 22:47:03)
> The only usage of m2m_ops is to pass its address to v4l2_m2m_init(),
> which  takes a pointer to const v4l2_m2m_ops as argument. Make it const
> to allow the compiler to put it in read-only memory.
