Russell King f40b121d98 [ARM] Rename ISA mach/dma.h header to mach/isa-dma.h
This avoids confusion with platform specific DMA implementations in
mach/dma.h

Russell King c72e005b09 [ARM] fix constant values of MAX_DMA_ADDRESS
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.

Russell King b9c78022b0 [ARM] move MAX_DMA_ADDRESS to mach/memory.h
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.

Russell King 47190a3350 [ARM] shark: avoid polluting the kernel's namespace
Avoid unnecessarily pollution of the kernel's namespace by avoiding
mach/hardware.h in mach/io.h.  Include this header file where necessary.

Nicolas Pitre b5ee900258 [ARM] remove a common set of __virt_to_bus definitions
Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

Russell King a09e64fbc0 [ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach
This just leaves include/asm-arm/plat-* to deal with.
