[PATCH 06/14] MIPS: OCTEON: add definitions for setting up SSO

From: Janne Huttunen <janne.huttunen at nokia.com>

Some Octeon II models have SSO instead of POW and use a different register
for setting the interrupt thresholds. Add the necessary definitions for
configuring the interrupts also on those models.
