firmware: imx: Add stub functions for SCMI LMM API
[ Upstream commit 3fb91b5c86d0fb5ff6f65c30a4f20193166e22fe ]
To ensure successful builds when CONFIG_IMX_SCMI_LMM_DRV is not enabled,
this patch adds static inline stub implementations for the following
functions:
- scmi_imx_lmm_operation()
- scmi_imx_lmm_info()
- scmi_imx_lmm_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.
