This arm_big_little_dt binding is incomplete and was never used. Commit f174e49e4906 ("cpufreq: remove unused arm_big_little_dt driver") removes the driver supporting this binding. However the binding was left unnoticed, so let's get rid of it now. Cc: "Rafael J.

While I was searching references to big-little that can be removed, I spotted this. Sorry for that.
