Yes, I understand. I myself is not convinced that we need one. Jassi
disagrees to add support to use each bit as doorbell in the ARM MHU
driver though the MHU specification states it clearly(3.4.4 Message
Handling Unit (MHU) of Juno TRM)[1].

This shim was added to deal with that with I agree is wrong IMO but
Jassi thinks that's right way to deal with it.
