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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
