media: rzg2l-cru: Add function pointer to configure CSI

Browse Source 
Add a `csi_setup` function pointer to the `rzg2l_cru_info` structure and
pass it as part of the OF data. On RZ/G3E and RZ/V2H(P) SoCs, additional
register configurations are required compared to the RZ/G2L SoC.

Modify `rzg2l_cru_csi2_setup()` to be referenced through this function
pointer and update the code to use it accordingly.

This change is in preparation for adding support for RZ/G3E and RZ/V2H(P)
SoCs.
