SPMD: add SPM dispatcher based upon SPCI Beta 0 spec
This patch adds a rudimentary SPM dispatcher component in EL3.
It does the following:
- Consumes the TOS_FW_CONFIG to determine properties of the SPM core
component
- Initialises the SPM core component which resides in the BL32 image
- Implements a handler for SPCI calls from either security state. Some
basic validation is done for each call but in most cases it is simply
forwarded as-is to the "other" security state.
