MIPS: Enable GENERIC_CPU_AUTOPROBE
Add missing macros and methods that are required by
CONFIG_GENERIC_CPU_AUTOPROBE: MAX_CPU_FEATURES, cpu_have_feature(),
cpu_feature().
Also set a default elf platform as currently it is not set for most MIPS
platforms resulting in incorrectly specified modalias values in cpu
autoprobe ("cpu:type:(null):feature:...").
Export 'elf_hwcap' symbol so that it can be accessed from modules that
use module_cpu_feature_match()
