Now that the common header defines everything and the SPI drivers are
using it, we can drop these duplicated global namespace polluters.

The common bfin_sport.h header now has unified definitions of these, so
stop polluting the global namespace.

The standard short name for control is CTL and not CTRL.  Use TWI0_xxx
even on parts that only have one TWI bus to keep things simple.  Drop
all the cdef helpers since the bus driver takes care of everything.

Now that there's a common header with everything unified, drop the defines
from the global namespace.  Pollution sucks.

Every Blackfin variant has the same DMA bit masks, so avoid duplicating
them over and over in each mach header.

There are no MXVR device drivers, and if someday there is, we can put
these in a dedicated header rather than polluting the global namespace.

The watchdog code doesn't need these, and the other parts had these
punted, so keep the global namespace clean.

The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as
the other ports on the part and the same way as all other Blackfin parts.
The MMRs are programmed slightly different and they cannot be used to
generate interrupts or wakeup a sleeping system.  Since these guys don't
fit into the existing code, create a simple gpiolib driver for them.

Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.

It also removes:
 - verbose GPL text(refer to the top level ./COPYING file)
 - file names (you are looking at the file)
 - bug url (it's in the ./MAINTAINERS file)
 - "or later" on GPL-2, when we did not have that right

It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

Add some defines to make the BF538/BF561 look like most other Blackfin
parts in that it has a MDMA0 channel available for low level init.
