A recent commit removed the only use of ipa_cmd_dma_task_32b_addr_add().
This function (and the IPA immediate command it implements) is no
longer needed, so get rid of it, along with all of the definitions
associated with it. Isolate its removal in a commit so it can be
easily added back again if needed.

One TX endpoint (per EE) is used for issuing immediate commands to
the IPA. These commands request activites beyond simple data
transfers to be done by the IPA hardware. For example, the IPA is
able to manage routing packets among endpoints, and immediate commands
are used to configure tables used for that routing.
Immediate commands are built on top of GSI transactions. They are
different from normal transfers (in that they use a special endpoint,
and their "payload" is interpreted differently), so separate functions
are used to issue immediate command transactions.
