This changes a struct name. The related code is conditionally
compiled and won't work because the include file linux/gpio-decoder.h
is missing, so removing this code would be an even better solution.
If the missing include file is added, it must fix the spelling, too.

The defBF512.h header exists only to include defBF51x_base.h, and it is
the only place where defBF51x_base.h is included. So move the contents
of the defBF51x_base.h header into the defBF512.h header.
Same situation for the other def/cdef pairs.

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.

Use the same naming convention for DMA traffic MMRs (most were legacy
anyways) so we can avoid useless ifdef trees.
Same goes for MDMA names -- this actually allows us to undo a bunch of
ifdef redirects that existed for this purpose alone.

Soon resource data will get automatically
populated from a set of autogenerated data
from TI's hardware database for the OMAP
platform.
Such database, might not have resources at
the expected order by the current drivers.
While we could hack in some exceptions to
that tool to generate resources in a specific
order, it seems less fragile to use the
resource name instead. That way, no matter
what order the resources are generated, the
driver still work.
Modified the OMAP, Blackfin and Davinci
architecture files to add the name of the IRQs
in the resource structures and musb driver to
use the platform_get_irq_byname() api to get
the device and dma irq numbers instead of using
the index.

Rename h/w IRQ flags handling functions to be in line with what is expected for
the irq renaming patch. This renames local_*_hw() to hard_local_*() using the
following perl command:
perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"`
and then fixing up asm/irqflags.h manually.
Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both
return the flags rather than passing it through the argument list.
