firmware: imx: Add stub functions for SCMI CPU API
To ensure successful builds when CONFIG_IMX_SCMI_CPU_DRV is not enabled, this patch adds static inline stub implementations for the following functions: - scmi_imx_cpu_start() - scmi_imx_cpu_started() - scmi_imx_cpu_reset_vector_set() These stubs return -EOPNOTSUPP to indicate that the functionality is not supported in the current configuration. This avoids potential build or link errors in code that conditionally calls these functions based on feature availability.
