ATF recently began announcing PSCI v1.1. Since that version is unknown to u-boot, the PSCI device nodes were not updated.
Switch from the case statement to a greater/less-than comparison so that v1.1, as well as future versions, get at least the compatible nodes of known versions.
PSCI v1.1 doesn't seem to have introduced a new corresponding compatible.
