Use the newly added callback for accelerated noinc MMIO to provide writesb, writesw, writesl, writesq, readsb, readsw, readsl and readsq. A special quirk is needed to deal with big endian regmaps: there are no accelerated operations defined for big endian, so fall back to calling the big endian operations itereatively for this case. The Hexagon architecture turns out to have an incomplete <asm/io.h>: writesb() is not implemented. Fix this by doing what other architectures do: include <asm-generic/io.h> into the <asm/io.h> file.
