ARM: stub out read_cpuid and read_cpuid_ext for CPU_CP15=n
Traditionally for !CPU_CP15 read_cpuid and read_cpuid_ext returned the
processor id independent of the parameter passed in. This is wrong of
course but theoretically this doesn't harm because it's only called on
machines having a cp15.
Instead return 0 unconditionally which might make unused code paths be
better optimizable and so smaller and warn about unexpected usage.
