[PATCH v2 01/15] x86: Rename struct cpu_policy to struct old_cpuid_policy

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

We want to merge struct cpuid_policy and struct msr_policy together, and the
result wants to be called struct cpu_policy.

The current struct cpu_policy, being a pair of pointers, isn't terribly
useful.  Rename the type to struct old_cpu_policy, but it will disappear
entirely once the merge is complete.

No functional change.
