[RFC PATCH kernel 07/17] x86/dma: Revert "x86: Remove unnecessary architecture-specific <asm/device.h>"

[Alexey Kardashevskiy]

The trusted guest device DMA setup is going to distinguish
encrypted and decrypted memory and dev_archdata is a logical place for
it.

This reverts commit c256d2a8adf2f5670ca262979c451ec4c1108e38.
