ARM: v6k: introduce CPU_V6K option
Introduce a CPU_V6K configuration option for platforms to select if they
have a V6K CPU core. This allows us to identify whether we need to
support ARMv6 CPUs without the V6K SMP extensions at build time.
Currently CPU_V6K is just an alias for CPU_V6, and all places which
reference CPU_V6 are replaced by (CPU_V6 || CPU_V6K).
Select CPU_V6K from platforms which are known to be V6K-only.
