n1sdp: use single SDS for mem_info and multichip info
Created by: manish-pandey-arm
Merge mem_info and multichip information into a single data structure which will be passed on to TF-A.
This patch introduces a new SDS to store platform information, which will be populated dynamically by SCP.
This structure holds following information:
- multichip_mode
- slave_count
- local_ddr_size
- remote_ddr_size
