arm: layerscape: Disable erratum A009007 on LS1021A, LS1043A, and LS1046A This erratum is reported to cause problems on these processors [1-3]. The problem is usually with the clocking, which is supposed to be configured by the RCW [4]. However, if it is not set, or if the default clocking is not correct, then this erratum will cause an SError. However, according to Ran Wang in [1]: " ... this erratum is used to pass USB compliance test only, you could disable this workaround on your board if you don't any USB issue on normal use case, I think it's fine." So just disable this erratum by default for these processors.
