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.
