Blackfin: add workaround for anomaly 05000171

DESCRIPTION:
The Boot ROM is executed at power up/reset and changes the value of the
SICA_IWR registers from their default reset value of 0xFFFF, but does not
restore them.

WORKAROUND:
User code should not rely on the default value of these registers.  Set
the desired values explicitly.
