Update quad power off so HB can call it on Slave Quads
Previously this HWP was only being called by the SBE down the MPIPL but we also need to call it during HB to power down the slave quads. There is a tricky workaround in this HWP where we need to save off some ring data EQ pointers for the PB. On the SBE we just saved the rings in global variables but we cannot do that in HB because the Hcode would not have access to the global varibles. Instead we will write the ring data to the OCC SRAM to do this I will just pass the data out of the hwp via an out param The same ring data is fetch during cache_initf procedure to init Change-Id: I4f20cd8dd9ca1b53604db1bc3020c0d57bbd1172 Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/36828 Tested-by: Jenkins Server <pfd-jenkins+hostboot@us.ibm.com> Tested-by: PPE CI <ppe-ci+hostboot@us.ibm.com> Tested-by: Hostboot CI <hostboot-ci+hostboot@us.ibm.com> Reviewed-by: Matt K.
