EAP peer config: Move ocsp param to phase1/phase2

OCSP configuration is applicable to each instance of TLS-based
authentication and as such, the configuration might need to be different
for Phase 1 and Phase 2. Move ocsp into struct eap_peer_cert_config and
add a separate ocsp2 network profile parameter to set this for Phase 2.
