NAK.  It's the entire register definitions for the PL08x, which we really
should not be exporting to common code.

Please wait until _after_ my DMA engine stuff (which is now in linux-next)
makes its way upstream before touching any of this stuff, otherwise there's
going to be conflicts.

As part of my patch series, this gets rid of a number of uses of it in
arch/arm, but there's still the .cctl_memcpy initializer which does. I've
not yet checked whether all implementations use the same value (they
probably do), and if so then it should be eliminated from platform code
and moved into the driver.

I've talked about asm/hardware/pl080.h within the last week on this very
thread... and it's disappointing to have to re-say what I said because
you've not read my previous postings.
