Yeah, this is in some sense trading the dependency on SWIOTLB for a
dependency on HAS_DMA:
Q1. I'm unable to envision a scenario where SWIOTLB without HAS_DMA
would make sense but I'm also expecting one of the kernel test bots
to try such a nonsensical configuration... should
the (unmodified) DMA address to derive the
original virtual address and re-encrypt the pages.

Through swiotlb_unencrypted_base.
P.S. I'm on vacation for the next couple of weeks starting next Monday;
Dexuan/Michael should be able to address review feedback in that period.
