FWIW this needs some more work on the Linux side, the IPA driver
currently hardcodes a reference to IMEM, which has a different
base between these two SoCs.
The IMEM region doesn't seem to be used as of current, but things
will explode the second it is.
A long overdue update would be to make the IPA driver consume
a syscon/memory-region-like property pointing to IMEM (or a slice
of it, maybe Alex knows what it was supposed to be used for).
