Introduce CONFIG_HAS_DMA
Architectures that don't support DMA can say so by adding a config NO_DMA
to their Kconfig file. This will prevent compilation of some dma specific
driver code. Also dma-mapping-broken.h isn't needed anymore on at least
s390. This avoids compilation and linking of otherwise dead/broken code.
Other architectures that include dma-mapping-broken.h are arm26, h8300,
m68k, m68knommu and v850. If these could be converted as well we could get
rid of the header file.
