[iMX] Fix .bbappend name due to NXP layer update
Rename imx-sc-firmware%.bbappend due to manifest update. NXP moved their repos from CodeAurora to GitHub and the commit that is pointed by the manifest to fix this has an updated version of the imx-sc-firmware recipe (from 1.2.7.1 to 1.2.10.1).
NOTE: this MR requires the MR pub/i.mx/yocto/seco-yocto-manifest!1 (merged) to be merged, otherwise there will be a version mismatch of the recipe.
