The serial TX IRQ is not simply (RX IRQ + 1) on some Blackfin chips,
so move the values to the platform resources.

IRQF_SHARED is not part of the IORESOURCE_IRQ bits. It's expressed by
IORESOURCE_IRQ_SHAREABLE.
IORESOURCE_IRQ_HIGHEDGE and IRQF_TRIGGER_HIGH are contradicting
values, an interrupt can hardly be configured for both level and edge
at the same time. This was introduced in commit 45138439(Blackfin
arch: flash memory map and dm9000 resources updating) of course
without any hint in the changelog what the heck this is supposed to
do.

The default for the Blackfin SPI driver is 8 bits and dma disabled,
so many of the bfin5xx_spi_chip resources are redundant. So punt
those parts.
Further, drivers should themselves be declaring 16 bit transfers,
so for those that do, and for the ones which no longer do 16 bit
transfers, drop the bfin5xx_spi_chip resources.

Now that the serial code has been unified in bfin_serial.h, and the
Blackfin UART driver pushed its resources to the boards files, we
don't need these headers anymore.

These files had a lot of whitespace damage, mostly due to copying and
pasting original files that had damage.
The BF561 header also had a lot of unused CONFIG_DEF_xxx defines, so
punt them all.

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.

We don't want the BF533 to be different in terms of its MMR headers, so
merge the FIO_FLAG helpers back into the normal place. To avoid circular
dependencies with headers, turn the inline C funcs into CPP defines. Not
like there will be any code size differences.

We don't want people banging on MMRs directly. As for the ip0x board,
it shouldn't need to muck with the CS pin directly as the Blackfin SPI
bus master driver takes care of driving this.

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.

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

With the recent kernel update the isp1362-hcd driver evaluates the
IORESOURCE_IRQ resource flags and requests the irq with the given
polarity/edge settings. However the ISP1362 config requires low
level/edge interrupts. Most of the Blackfin boards use some random
flag or no flag at all. Make all boards use a know good flag
IORESOURCE_IRQ_LOWEDGE.

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.

Split the BF532 machine type BFIN_*_FIO_FLAG() functions to their own header
file to avoid circular #include problems as these functions require IRQ flag
handling, which requires asm/blackfin.h, which otherwise requires the header
file that defines these functions.
For good measure, also get rid of the inclusion of asm/blackfin.h from
mach/cdefBF532.h (which is circular) and defBF532.h (which is included by
asm/blackfin.h before including this header).
