Fix the various misspellings of "system", controller", "interrupt" and
"[un]necessary".

consistent_sync() is used to handle the cache maintainence issues with
DMA operations.  Since we've now removed the misuse of this function
from the two MTD drivers, rename it to prevent future mis-use.

We don't currently support the noncoherent DMA API, but it needs to
be provided for kernels with devres to link.

The DMA cache handling functions take virtual addresses, but in the
form of unsigned long arguments.  This leads to a little confusion
about what exactly they take.  So, convert them to take const void *
instead.

dma_is_consistent() is ill-designed in that it does not have a struct
device pointer argument which makes proper support for systems that consist
of a mix of coherent and non-coherent DMA devices hard.  Change
dma_is_consistent to take a struct device pointer as first argument and fix
the sole caller to pass it.
