If the renamed symbol is defined lib/iomap.c implements ioport_map and
ioport_unmap and currently (nearly) all platforms define the port
accessor functions outb/inb and friend unconditionally.  So
HAS_IOPORT_MAP is the better name for this.

Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.

The motivation for this change is to reintroduce a symbol HAS_IOPORT
that signals if outb/int et al are available.  I will address that at
least one merge window later though to keep surprises to a minimum and
catch new introductions of (HAS|NO)_IOPORT.

The changes in this commit were done using:

	$ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

Strictly speaking this call is a no-op on the platform where dcscb.c is
used since it only has architected caches.  The call was there as a hint
to people inspired by this code when writing their own backend, but the
hint might not always be correct.

For example, if a PL310 were to be used it wouldn't be safe to call
the regular outer_flush_all() as atomic instructions for locking
are involved in that case and those instructions cannot be assumed to
still be operational after v7_exit_coherency_flush() has returned.
Given no other CPUs (in the cluster) should be running at that point
then standard concurrency concerns wouldn't apply.

So let's simply kill this call for now and enhance the existing comment.

Export the DMA register information from the SoC specific data, such
that we can access the registers directly in omap-dma.c, mapping the
register region ourselves as well.

Rather than calculating the DMA channel register in its entirety for
each access, we pre-calculate an offset base address for the allocated
DMA channel and then just use the appropriate register offset.
