Vikram Kanigiri 50e27dadbc Rework the TSPD setup code
There is no mechanism which allows the TSPD to specify what SPSR to
use when entering BL3-2 instead of BL3-3. This patch divides the
responsibility between tspd_setup() and tspd_init() for initializing
the TSPD and TSP to support the alternate BL3-2 initialization flow
where BL3-1 handsover control to BL3-2 instead of BL3-3.
SPSR generated by TSPD for TSP is preserved due the new division of
labour which fixes #174.

This patch also moves the cpu_context initialization code from
tspd_setup() to tspd_init() immediately before entering the TSP.
Instead tspd_setup() updates the BL3-2 entrypoint info structure
with the state required for initializing the TSP later.

Fixes  ARM-software/TF-issues#174
