KVM: PPC: Make EPCR a valid field for booke64 and bookehv

In BookE, EPCR is defined and valid when either the HV or the 64bit category are implemented. Reflect this in the field definition. Today the only KVM target on 64bit is HV enabled, so there is no change in actual source code, but this keeps the code closer to the spec and doesn't build up artificial road blocks for a PR KVM on 64bit.
