Linus Torvalds 009fbfc97b dma-mapping updates for Linux 6.7
- get rid of the fake support for coherent DMA allocation on coldfire with
    caches (Christoph Hellwig)
  - add a few Kconfig dependencies so that Kconfig catches the use of
    invalid configurations (Christoph Hellwig)
  - fix a type in dma-debug output (Chuck Lever)
  - rewrite a comment in swiotlb (Sean Christopherson)
