According to Nordic Semiconductor Product Anomaly Notice (document NRF51822-PAN), item 16, some revisions of nRF51822 sometimes reset without all RAM blocks enabled. This was noted on NRF51822-QFAA rev CA/C0, only 8KiB of memory was accessible. This patch turns on all RAM following a debugger induced reset (matches specified behaviour.)
