The main asm/blackfin.h header will pull in mach/blackfin.h to get
all the fun Blackfin defines. So having any of the sub-mach headers
trying to include asm/blackfin.h makes no sense -- punt it.
The mach/blackfin.h header takes care of including the part-specific
def headers which in turn will include any other needed def file.
Similarly, it takes care of pulling in the part-specific cdef header.
So move this logic out of the blackfin.h when necessary.
Further, make sure the cdef headers do not waste time including the
def headers again.
Since all parts need the common def/cdef headers, move this logic
out of the part-specific headers and into the mach/blackfin.h file.
Finally, we need to split the BF539 def header since the BF538 does
not have MXVR and we don't want to expose those MMRs.
So now all parts should have the same behavior:
mach/blackfin.h
asm/def_LPBlackfin.h
part-specific def.h
if ! asm
asm/cdef_LPBlackfin.h
part-specific cdef.h
And the sub def/cdef headers only tail into what they need.

Each Blackfin port has been duplicating UART structures and defines when
there really is no need for it. So start a new bfin_serial.h header to
unify all these pieces and give ourselves a fresh start.

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).

Many aspects of the Blackfin memory map is exactly the same across all
variants. Rather than copy and paste all of these duplicated values in
each header, unify all of these into the common Blackfin memory map header
file. In the process, push down BF561 SMP specific stuff to the BF561
specific header to keep the noise down.

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.
