Kindly check patch 6/6, it is introducing bam node with 7iommus which IP
describes and hence, updated bindings before to accustom this which also
helps in avoiding rob's dt-schema bot error.
The same way we add qcom,shikra* compatible before consuming in DT,
isn't this case also similar where bindings are updated as per the DT
changes?

Shikra bam actually has 7 iommus and hence, bindings need an update.
