As part of the ETSI preCAC feature, every 20MHz channel that is CACed and not in NOL is maintained in a list which is then checked during every channel switch for CAC reuse (avoiding CAC). With the introduction of preCAC list (Binary Search Forest) for 20, 40 and 80MHz channels which also includes the current channel CAC information, the ETSI preCAC list has become redundant. Remove all APIs and changes that support the redundant ETSI preCAC list. Change-Id: I76656807bc117af1f6909160ade86ae13d390f1a CRs-Fixed: 2484864
