media: dt-bindings: add NXP i.MX93 compatible string

The i.MX93 uses the DW CSI-2 RX controller, which is similar to the
Rockchip RK3568 implementation.

The i.MX93 variant provides one IRQ, two clocks, and no resets. Add the
"fsl,imx93-mipi-csi2" compatible string and keep the same constraints for
RK3568.
