media: synopsys: Fix IPI using hardcoded datatype

The imx93_csi2rx_dphy_ipi_enable() function configures the IPI datatype
using csi2->formats->csi_dt, which is initialized during probe but never
updated in set_fmt(). This causes the IPI to always use the probe-time
default datatype, ignoring the actual media bus format negotiated at
runtime. When userspace requests a different format, the IPI hardware is
configured with the wrong datatype, resulting in incorrect image output.

Fix by updating csi2->formats in the set_fmt callback to reflect the
currently negotiated format, ensuring the IPI configuration matches the
runtime datatype.
