No code uses these, and the short define names are polluting the global
namespace where they collide with things like common irq files. So just
punt the damned things. If in the future we need HDMA support, we can
make a standalone header for these things.

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.

Some peripherals might generate an error interrupt shortly after the
data interrupt due to the fact that the peripheral isn't serviced fast
enough. In most cases this isn't a problem and is expected behavior.
This hasn't been a problem on most parts since you simply don't request
the error interrupt (or you leave it disabled while there is an expected
state) and do the peripheral status checking in the data interrupt.
The Blackfin SIC allows people to prioritize data and error interrupts,
and the Blackfin CEC allows interrupts of equal or higher priority to
nest. The current default settings gives error interrupts a higher
priority than data interrupts. So if an error occurs while processing
the data interrupt, it will be serviced immediately.
However, the error interrupt on the BF537 SIC cannot be enabled on a
per-peripheral basis. Once the error interrupt is enabled for one
peripheral, it is automatically enabled for all peripherals.
Therefore lower the default multiplexed error interrupt priority so
most people need not worry themselves with this issue.

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.

This patch provides infrastructure for MAC Wake-On-Lan and PHYINT use in
phylib. New Interrupts added:
IRQ_MAC_PHYINT /* PHY_INT Interrupt */
IRQ_MAC_MMCINT /* MMC Counter Interrupt */
IRQ_MAC_RXFSINT /* RX Frame-Status Interrupt */
IRQ_MAC_TXFSINT /* TX Frame-Status Interrupt */
IRQ_MAC_WAKEDET /* Wake-Up Interrupt */
IRQ_MAC_RXDMAERR /* RX DMA Direction Error Interrupt */
IRQ_MAC_TXDMAERR /* TX DMA Direction Error Interrupt */
IRQ_MAC_STMDONE /* Station Mgt. Transfer Done Interrupt */
On BF537/6 the implementation is not straight forward since there are now
two chained chained_handlers. A cleaner approach would have been to add
latter IRQs to the demux of IRQ_GENERIC_ERROR.
