early serial init also utilizes the peripheral request api - however
at this point bfin_gpio_init didn't allocate memory for the labels.

[Blackfin] arch: fix bug - trap_tests fails to recover on some tests.

http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3719

When the CPLBs get a miss, we do:
  - find a victim in the HW table
  - remove the victim
  - find the replacement in the software table
  - put it into the HW table.

If we can't find a replacement in the software table, we accidently
leave a duplicate in the HW table. This patch ensures that duplicate
is marked as not valid.

What we should do is find the replacement in the software table, before
we find a victim in the HW table - but its too late in the release cycle
to do that much restructuring of this code.

Rather that duplicate code, connect Hardware Errors (irq5) into trap_c,
so user space processes get killed properly.

The rest of irq_panic() can be moved into traps.c (later)

There is still a small corner case that causes problems when a
pheriperal interrupt goes off a single cycle before a user space
hardware error. This causes a kernel panic, rather than the user
space process being killed.

But, this checkin makes things work in 99.9% of the cases, and is a vast
improvement from what is there today (which fails 100% of the time).

* Currently this driver is broken: cris_dma_on() (returns 'int')
  is assigned to hwif->dma_host_on (returns 'void') so the driver
  won't build.

* ->ide_dma_on method was missing so the driver OOPS-es on attempt
  to enable DMA.

* drive->using_dma was never set/cleared so DMA wouldn't be used anyway.

Unfortunately it seems that ide-cris stays broken even after this patch:

* V10: <asm/arch-v10/ide.h> needs fixing
  - ide_init_default_hwifs() should be removed
