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 Change-Id: Ida0a8a48d466c71d5b07b8c7f2af169b73f96940
