soc/intel: common,skl,cnl,icl: drop reserved mmio memory size calculation
Remove the calculation of the Reserved Intel MMIO Memory size from systemagent and memmap, since it is not needed. The size is used in SA to calculate the space between cbmem_top and TSEG without DPR and Chipset Reserved Memory. Since this will always be equal to 0, the reservation will be skipped and TSEG, DPR and Chipset Reserved Memory will get reserved alltogether. By reading the code and pratical testing we figured out that: - TSEG - DPR - reserved - top_of_memory == 0 - TSEG - DPR - reserved == top_of_memory This means the whole block will never reserve anything because it is always 0. Hence the code can be removed for simplification.
