Add support for BL3-1 as a reset vector
This change adds optional reset vector support to BL3-1
which means BL3-1 entry point can detect cold/warm boot,
initialise primary cpu, set up cci and mail box.
When using BL3-1 as a reset vector it is assumed that
the BL3-1 platform code can determine the location of
the BL3-2 images, or load them as there are no parameters
that can be passed to BL3-1 at reset.
It also fixes the incorrect initialisation of mailbox
registers on the FVP platform
This feature can be enabled by building the code with
make variable RESET_TO_BL31 set as 1
