With the introduction of FEAT_RME MDCR_EL3 bits NSPB and NSPBE depend on each other. The enable code relies on the register being initialised to zero and omits to reset NSPBE. However, this is not obvious. Reset the bit explicitly to document this. Similarly, reset the STE bit , since it's part of the feature enablement.
