This config option allows to add RTC fast memory region to system heap with capability
similar to that of DRAM region but without DMA. This memory will be consumed first per
heap initialization order by early startup services and scheduler related code. Speed
wise RTC fast memory operates on APB clock and hence does not have much performance impact.
