There is a typo and grammar mistake in agentserviceconfig crd details. Here is the output:

$ oc get crd agentserviceconfigs.agent-install.openshift.io -oyaml | less
mirrorRegistryRef:                 description: |-                   MirrorRegistryRef is the reference to the configmap that contains mirror registry configuration                                                      In case no configuration is need, this field will be nil. ConfigMap must contain to entries:                                                         ca-bundle.crt - hold the contents of mirror registry certificate/s                                                                                   registries.conf - holds the content of registries.conf file configured with mirror registries

As you can see it should be:
1. In case no configuration is needed (needed instead of need)
2. ConfigMap must contain two entries (two instead of to)
