Copied the ip_arria10_e2sg/ram/ip_arria10_e2sg_<ram_name>.vhd file and copied...

Copied the ip_arria10_e2sg/ram/ip_arria10_e2sg_<ram_name>.vhd file and copied in the component declaration and instance example from generated/ram_2port_2040/sim/ip_agi027_xxxx_ram_<ram_name>_ram_2port_2040_<generated_hash>.vhd. Updated information header. Changed the technology_name from ip_arria10_e2sg to ip_agi027_xxxx. Checked the differences between the underlying files where the original vhd file is based on. There are no significant differences. Most of the parameters that are different are added and commented out.
