The command was already tagged as deprecated in 2015 with commit0df5577282("armv7a: remove l1 flush all data handler") but has never been removed. An equivalent command 'cache l2x conf' was introduced at the same time in commitcd440bd32a("add armv7a_cache handlers"). Drop it and deprecate it. Replace the old command in the Tcl script.
