replace C284 with 3x 100uF capacitors to avoid P1V2 spurious shutdown
Paul noticed on Spexi7U that for a few boards and after some time of operation using DDR memories, 1.2V channel would be shut down by the IRPS. This was caused by the regulation loop becoming unstable. The fix is to replace the C284 (220uF) capacitor with 3 parallel 100uF capacitors.
