Older on-chip Blackfin bootroms do not create a dummy NMI handler, so set
up one ourselves when anomaly 05000219 applies.

Need to reload the loop counters to keep from corrupting hardware loops.

If the memory layout pushes the stack out of the default DCPLB coverage,
the exception handler may trigger a double fault by trying to push onto
the uncovered stack. So handle the exception stack similar to the kernel
by using the top of the scratch pad SRAM.

All of the duplicated code for Blackfin processors and boot modes have been
unified. After all, the core is the same for all processors, just the
peripheral set differs (which gets handled in the drivers).
