drm: renesas: Extend RZ/G2L supported KMS formats

The RZ/G2L driver utilises the VSPD to read data from input sources.

The rzg2l_du_kms component lists a restricted subset of the capabilities
of the VSPD which prevents additional formats from being used for
display planes.

The supported display plane formats are mapped in rzg2l_du_vsp_formats[].

Extend the rzg2l_du_format_infos[] table with the corresponding mappings
between the supported DRM formats and the formats exposed by the VSP in
rzg2l_du_vsp_formats, maintaining the same ordering in both tables.

The RPF module on VSPD supports various format conversion and send the
image data to BRS(Blend ROP Sub Unit) for further processing.
