[PATCH 2/2] powerpc/machdep: Drop include of dma-mapping.h

[Michael Ellerman]

Drop the include of dma-mapping.h in machdep.h, replace it with forward
declarations of struct device and struct pci_dev, and include time64.h
and page.h which are required for time64_t and pgprot_t respectively.

Add direct includes of some other headers to some files that were
getting them via machdep.h.
