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
