Populate BL31 input parameters as per new spec
This patch is based on spec published at
https://github.com/ARM-software/tf-issues/issues/133
It rearranges the bl31_args struct into
bl31_params and bl31_plat_params which provide the
information needed for Trusted firmware and platform
specific data via x0 and x1
On the FVP platform BL3-1 params and BL3-1 plat params
and its constituents are stored at the start of TZDRAM.
The information about memory availability and size for
BL3-1, BL3-2 and BL3-3 is moved into platform specific data.
