lib: fdtdec: Update ram_base to store ram start adddress

Browse Source 
This patch updates the ram_base to store the start address of
the first bank DRAM and the use this ram_base to calculate ram_top
properly. This patch fixes the erroneous calculation of ram_top
incase of non zero ram start address.
