Rework memory information passing to BL3-x images
The issues addressed in this patch are: 1. Remove meminfo_t from the common interfaces in BL3-x, expecting that platform code will find a suitable mechanism to determine the memory extents in these images and provide it to the BL3-x images. 2. Remove meminfo_t and bl31_plat_params_t from all FVP BL3-x code as the images use link-time information to determine memory extents. meminfo_t is still used by common interface in BL1/BL2 for loading images Change-Id: I4e825ebf6f515b59d84dc2bdddf6edbf15e2d60f
