Add flag in qcom_adsp private data structure and initialize
it to distinguish ADSP and WPSS modules for using iommu selectively.
There are other flags available to distinguish between ADSP and WPSS
like 'is_wpss'. So you probably want to tweak your commit message to
just say if it has a iommu in front of it or not and skip referencing
WPSS.
