Currently, a lot of code is handling dma_addr_t values as if they
unconditionally hold CPU addresses. However, this is not true for every
architecture. For example, MIPS requires an explicit conversion from a
physical address space to a virtual address that corresponds to some
(currently used one in our case) address space segment for this pointer
to be valid and usable. Another issue is that DMA ranges, specified in
device trees, will not work this way. To get from a virtual address to
a dma handle and vice versa we need to add/subtract some offset, which
is calculated from "dma-ranges" property. As it seems, no driver
actually uses this at the moment, but as there exists code that does
this conversions, which is used in dma_map_single(), it seems reasonable
to utilize it for dma_sync_single_for_*() too.
I wonder if there are some actual use cases that would not be properly
covered by this change, for example if there are dma/cpu conversions
that we may have to do in architecture-specific code and which require
virtual addresses. For those, we cannot have dma_sync_single_for_*
functions that just call arch_sync_single_for_* only for the CPU cache
syncronization part, i.e. we would have to do all dma/cpu conversions in
arch-specific code, unlike how it is done in this patch. This would
lead to some code duplication though.
TODO: dma_alloc/free_coherent do need same kind of changes to utilise
cpu/dma conversions properly

With the previous commit that changes dma_sync_single_for_* API, every
callsite that uses it needs to be updated. Driver code is now required
to pass a corresponding pointer to device struct as the first argument.
Some drivers don't seem to have an appropriate device handle handy, so
just use NULL for those. This should not make any functional change, as
there is no driver at the moment that requires non 1-to-1 dma mappings,
and thus would actually utilize those device pointers.
