soc/intel/cannonlake: Use EBDA structure to store soc reserve memory size
Avoid calling calculate_dram_base() function to get chipset reserved memory size during pci resource allocation. Rather use EBDA to store chipset reserved memory size while calling cbmem_top_int(). This patch avoids one extra calculate_dram_base() call. BRANCH=none BUG=b:63974384 TEST=Ensures DRAM based resource allocation has taken care of Intel SoC reserved ranges.
