It's just a wrapper around ARM SMCs that don't exist on x86_64 either. :D But knowing how quickly qcom_scm causes compile problems on random kernel configurations I'm not going to suggest changing that... So, this looks good to me.

The introduction of __qcom_scm_set_boot_addr_mc() relies on cpu_logical_map() and MPIDR_AFFINITY_LEVEL() from smp_plat.h, but only ARM and ARM64 has this include file, so the introduction of this dependency broke compile testing on e.g. x86_64. Make the inclusion of smp_plat.h and the affected function depend on ARM || ARM64 to allow the code to still be compiled.
