Sean Anderson 881284b36a 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.
