media: renesas: vsp1: Add support for RZ/G2L VSPD
The RZ/G2L VSPD provides a single VSPD instance. It has the following sub modules MAU, CTU, RPF, DPR, LUT, BRS, WPF and LIF. The VSPD block on RZ/G2L SoCs does not have a version register, so added a new compatible string "renesas,r9a07g044-vsp2" with a data pointer containing the info structure. Also the reset line is shared with the DU module.
