As an alternative to the 3 individual handlers, there is also a simplifiedio mem hook function. To be consistent, let's add an endianness parameterthere too.

pci-host: Delegate bswap to mmio layer
The only reason we have bswap versions of the pci host code is thatmost pci host devices are little endian. The ppc e500 is the onlyodd one here, being big endian.
So let's directly pass the endianness down to the mmio layer and not...
