[PATCH] firmware: imx: sm-misc: Make scmi_imx_misc_ctrl_nb variable static

[Krzysztof Kozlowski]

File-scope 'scmi_imx_misc_ctrl_nb' is not used outside of this unit, so
make it static to silence sparse warning:

  sm-misc.c:19:23: warning: symbol 'scmi_imx_misc_ctrl_nb' was not declared. Should it be static?
