Document VSPD found in RZ/G2L and RZ/V2L family SoC's. VSPD block is
similar to VSP2-D found on R-Car SoC's, but it does not have a version
register and it has 3 clocks compared to 1 clock on vsp1 and vsp2.

This patch introduces a new compatible 'renesas,vsp2-rzg2l' to handle
these differences.

Please follow the recommended order <vendor>,[<family>|<soc>-]<function>,
