Subject: [PATCH V4 1/2] firmware: imx: add dummy functions
From: Peng Fan <peng.fan@....com>
IMX_SCU_SOC could be enabled with COMPILE_TEST, however there is
no dummy functions when CONFIG_IMX_SCU not defined. Then there
will be build failure.
So add dummy functions to avoid build failure for COMPILE_TEST
