[PATCH v14 01/10] iomap: Use correct endian conversion function in mmio_writeXXbe

[Logan Gunthorpe <logang@deltatee.com>]

The semantics of the iowriteXXbe() functions are to write a
value in CPU endianess to an IO register that is known by the
caller to be in Big Endian. The mmio_writeXXbe() macro, which
is called by iowriteXXbe(), should therefore use cpu_to_beXX()
instead of beXX_to_cpu().

Seeing both beXX_to_cpu() and cpu_to_beXX() are both functionally
implemented as either null operations or swabXX operations there
was no noticable bug here. But it is confusing for both developers
and code analysis tools alike.
