firmware: imx: remove duplicate scmi_imx_misc_ctrl_get()

These two functions have a stub definition when CONFIG_IMX_SCMI_MISC_EXT
is not set, which conflict with the global definition:

      |     ^~~~~~~~~~~~~~~~~~~~~~
include/linux/firmware/imx/sm.h:24:19: note: previous definition of 'scmi_imx_misc_ctrl_get' with type 'int(u32,  u32 *, u32 *)' {aka 'int(unsigned int,  unsigned int *, unsigned int *)'}

      |                   ^~~~~~~~~~~~~~~~~~~~~~

There is no real need for the #ifdef, and removing this avoids
the build failure.
