Right now this results in increased code, but I still think it is worth doing to avoid
replication across instances of drivers etc and move as much stuff as possible to constant.
Ops structure is optional for the occasional driver that uses none of it (currently
only the ad7793).

Message 'receive fifo overflow' appeared in the log. Root cause was an
invalid physical address being programmed into the DMA engine. This was
caused by an invalid pointer cast in the dma code. Issue was observed on
a Sparc (Sun Fire V120) machine but could theoretically also pop up
on other architectures.

Driver was tested to scan and ping on aforementioned machine.

Problem would pop up during driver load on a Sun Fire V120 and manifested
itself as an exception. This was caused by int* pointers provided to memcpy()
that were not aligned on an int boundary. The pointer type provided to
memcpy() is used by the compiler for optimization purposes. Fix was to cast
the int* pointers to void* pointers.

Certain Mips based, big endian Broadcom products contain a memory window
for endianness swap purposes. However, this is too system specific for
this driver as there are more big endian platforms to support. Thus, this
'window' functionality is not to be used and can be removed.

The swap window would be a performance improvement and could be provided
with a dedicated mapping function in the platform specific code.
