[POWERPC] CPM2: Reset the CPM when early debugging is not enabled.
Similarly to what is done for PQ1-based platforms, this patch resets the PQ2 Communication Processor Module in cpm2_reset() when early debugging is not enabled. This helps avoiding conflicts when the boot loader configured the CPM in an unexpected way.
