This is a preparitory patch to allow us to easily change the way we
add and lookup DMA channel structures.

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.
This allows us to remove a lot of mach/dma.h files which don't contain
any useful code. Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

Since 8d5796d2ec, we have allowed
PAGE_OFFSET to be configurable, so a constant virtual address
for MAX_DMA_ADDRESS is buggy. It should be defined in terms of
PAGE_OFFSET rather than a constant virtual address.

Move the definition of MAX_DMA_ADDRESS from mach/dma.h to mach/memory.h,
thereby placing it along side its relative, ISA_DMA_THRESHOLD.

ixp23xx's mach/io.h claims to need linux/kernel.h for BUG().
However, this header doesn't make use of BUG().
