Subject: [PATCH] firmware: qcom: scm: add error include

In some configurations the preprocessor define ENODEV is missing
leading to compile time errors (e.g. when using imx_v6_v7_defconfig).

I noticed while compiling todays master branch with imx_v6_v7_defconfig:

In file included from drivers/gpu/drm/msm/adreno/a5xx_gpu.c:17:
./include/linux/qcom_scm.h:73:10: error: use of undeclared identifier 'ENODEV'
        return -ENODEV;
                ^

I think this only got uncovered due to e6f6d63ed14c ("drm/msm: add headless
gpu device for imx5") but it seems to be a missing include already before that
commit.
