MIPS: Add -Werror to arch/mips/Kbuild
Adding subdirs-ccflags-y := -Werror to arch/mips/Kbuild let us in one go cover all files with -Werror. In addition this allows us to remove the individual -Werror definition in various Makefile. Adding the definition to Kbuild as a recursive option help us not to forget to do so. With this change we now compile arch/mips/kernel/cpufreq with -Werror One drawback: When specifying a subdirectory covered by the Kbuild file like this: make arch/mips/kernel/ then kbuild fails to pick up the -Werror definition.
