So, introduce a feature bit for handling the same. This patch also adds separate device info structure for V3M and V3H SoCs, as both these SoCs share the same model ID, but V3H does not have VSP1_HAS_NON_ZERO_LBA feature bit.

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.
