Subject: [PATCH] iwlwifi: acpi: move function to get mcc into acpi code
Git-commit: 45f65569e0d968c5fd1e8c3c6d8983b402caaa27
Patch-mainline: v4.15-rc1
References: FATE#326294
The iwl_get_bios_mcc() function was in the iwl-nvm-parse.c file, but
it has nothing to do with the NVM. Move it to fw/acpi.c and rename it
to iwl_acpi_get_mcc().
