firmware: imx: Add stub functions for SCMI CPU API
[ Upstream commit 222accf05fc42f68ae02065d9c1542c20315118b ]
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.
Fixes: 1055faa5d660 ("firmware: imx: Add i.MX95 SCMI CPU driver")
