Allow "Security Version" To Be Set For A Given Configuration

This commit allows for a given configuration/system to set an optional
"Security Version" value.  It specifically sets the value of the p10ebmc_defconfig
configuration to zero.  This value then gets passed into the openpower-pnor-p10
package and is built into the partitions/lids via the signing utilities.  This
commit points to the openpower PNOR repo's master-p10 commit that has the
needed support for this.
