media: renesas: vsp1: Make reset control optional to support platforms without a reset line
Switch the VSP1 driver to use devm_reset_control_get_optional_shared()
when requesting its reset control. Some newer Renesas SoCs integrating
VSP1 such as RZ/T2H do not provide a reset line for the VSP IP block.
